# The 9 Hole Challenge
* 9 code golfing challenges of varying difficulty.
* Penalties for using the same language more than once.
* The question will be updated with pars, hole champions and trophy winners.
*This comes from a competition I have with some friends, it's not the usual format, but I hope some of you will appreciate the different spin on it. Challenges, rules and trophies below.*
# Holes
1. # Greenway (24)
`f(c:string, n:integer)`  
Prints a line containing `n` instances of `c`.
2. # Somewhere in the Rough (73)
`f(t:string, s:string, n:integer) -> i`  
Where `i` is the index of the `nth` instance of `s` in `t`.
3. # Curry for Dinner (6235)
`f(x:function, y: function) -> g`
Where `g` is a function that will call `y`, `n` times;
where `n` is the return value of `x`
4. # Spew (92)
`f(p:string)`
Writes to file at `p` and fills it with a randomly sized rectangle of random characters (ascii).
5. # Treasure Hunt (75)
`f(p:string, c:char) -> (x, y)`
Reads file at `p` which contains a grid of symbols
and returns the `x` and `y` coordinates of the first instance of that symbol
within the grid, assume it exists.
6. # Bridge on the River Kwai (179)
`f(l:list[int])`
Prints difference bridges diagram for `l`. 
E.g for `[1,7,3,17,1]`
```
 /+6\ /-4\ /+14\  /-16\
1    7    3     17     1
```
Make sure that the spaces are created according to the size of the 
number above. For a 3 digit long number, you are going to need 4 spaces
between the digits on the line below.
Catch: Somewhere, your code must spell trousers
(Must have at least 1 non-alphanumeric delimiters. 
E.g. `tr(ou,se)(rs)`
7. # Time Flies When You're Playing Golf (1157)
`f(p:string) -> [h, m]`
Reads file at `p` which contains an ASCII representation
of an analogue clock, where the hour hand is represented
with one lines, and the minutes by two. Output a list 
containing two elements: the hours and minutes shown on
the clock. If only one hand is visible, assume both point
to that position.
Here are all the possible combinations for a hand.
```
\ | /
 \|/
--o--
 /|\
/ | \
```
These positions, respectively are (12, 1, 3, 5, 6, 7, 9, 11).
Assume that the other characters within the clock face are spaces.
8. # Timber! ()
`f(p:string) -> b:boolean`
Where p is the path to a file with an ascii building in.
Blocks with white space underneath them will fall.
(Except from slashes, which stay in place if there is a stable block in the opposite direction to the way they face). If the building is structurally integral
return true, otherwise return false. All non whitespace blocks
are counted as being solid and other than slashes, they all fall.

9. # Slacker News (218)
`f(s:string, r:string, p:string)`
Gets the titles of the top 20 stories on Hacker News and changes all instances of `s` to `r`, then writes the new titles to a html file at `p`, where each title is contained within a h1 element.
The outputted file should something like this
`<h1>Some title</h1></h1>Some other title</h1>...etc`
**Catch**: 
	* You may not use the HN api.
	* You may not use Regex.
	* You may not use angle braces anywhere in your code.

# Scoring
* Character count is the length of the function that will compile & run correctly. However you still need to submit the full code, including imports.
* **+10%** for every repeated language in your submission. (E.g. If you use Ruby for 3 solutions, then your final score will be multiplied by 1.2). Different versions of the same language count still count as the same language.
* Par will be average score for each hole.
* Submit your solutions in one answer.
* Your overall score is your character count + your language penalty, then round it up.

[Answer]
## Score: 1320
I've plenty to do to improve this score... Oh well, at least I avoided repeated-language penalties. :-)
### 1. Python (21 chars)
```
def f(c,n):print(c*n)
```
The "obvious" solution.
### 2. ECMAScript 6 (47 chars)
```
f=(t,s,n)=>t.split(s).slice(0,n).join(s).length
```
Finds the index in a bit of an unconventional way, by counting the length of the substring before it.
### 3. J (12 chars)
```
f=:2 :'v^:u'
```
The built-in conjunction `^:` raises a function to a power (i.e. repeats a function a given number of times). That is, `f^:3 y = f (f (f y)))`. However, it's overloaded to alos accept functions rather than integers, in which case it runs the function on the input to get the number of repetitions. Unfortunately we need to flip the operands for the task, otherwise we'd have the consise answer `f=:^:`.
### 4. C (95 chars)
```
#include <stdio.h>
#include <stdlib.h>
f(char*p){FILE*f=fopen(p,"a");for(int n=rand(),y=n*n;y--;y%n||putc(10,f))putc(rand()%94+32,f);}
```
This task leaves quite a bit of room for interpretation and abuse: is it okay to just output a random printable ASCII character and say it's a randomly-dimensioned rectangle with dimensions from the set {1}? Probably not. Anyway, I went with plain `rand()` but in reality you probably want to add `%9` or something if you want to test it. On my linux box I didn't have to flush the file in order for it to be written (I guess it flushes automatically on program exit), but I'm pretty sure you have to flush it to be standards-compliant, so feel free to add `fflush(f);` to the count here.
### 5. Haskell (100 chars)
```
import Control.Arrow
import Data.List
import Data.Tuple
import Control.Applicative
h p c=head.filter(p c.snd).zip[1..]
g c=swap.(id***fst.h(==)c).h elem c.lines
f p c=g c<$>readFile p
```
I like the repeated pattern between finding the row and the column (abstracted via `h`).
### 6. Lua (261 chars)
```
function f(s,m,y,...)if s and m then for i,v in pairs(m)do
io.write(v,(" "):rep(#tostring(s[i])))end print()elseif s then
r=unpack f(s,{"",f(trouse,r(s))})f({f(nil,r(s))},s)elseif y then
return ("/%s%d\\"):format(m<y and"+"or"-",math.abs(m-y)),f(s,y,...)end end
```
Makes use of multiple return values and recursion to deal with computing the differences. It cost me a few characters to match the sample output exactly (adding the right amount of spaces everywhere).
### 7. Go (307 chars)
```
func f(p string)[]int{var l[]string
g,_:=os.Open(p)
H,M,s,m:=0,0,bufio.NewScanner(g),[][]int{{-1,-1,11},{-1,0,12},{-1,1,1},{0,-1,9},{0,1,3},{1,-1,7},{1,0,6},{1,1,5}}
for s.Scan(){l=append(l,s.Text())}
for _,a:=range m{if l[2+a[0]*2][2+a[1]*2]!=' '{M=a[2]}
if l[2+a[0]][2+a[1]]!=' '&&(H==0||M!=a[2]){H=a[2]}}
return[]int{H,M}}
```
Could probably be golfed a lot more; I barely know Go.
### 8. CoffeeScript (+ node.js) (223 chars)
```
f=(p)->
 a=require('fs').readFileSync(p).toString().split "\n"
 U=(i,j)->a[i]?[j]and a[i][j]==' '
 for l,i in a
  for c,j in l
   m =
    "/":[i+1,j-1]
    "\\":[i+1,j+1]
    a:[i+1,j]
   return if U.apply(0,m[c]or m.a)
 1
```
A bit of a cheap-shot since I already have JS. Oh well. Returns a falsy value (namely, `undefined`) or a truthy value (namely, `1`) to indicate the answer.
### 9. Bash (254 chars)
```
f(){
curl https://news.ycombinator.com/rss|
awk -Ftitle '{OFS="h1\76\n\74h1";ORS="";print substr(OFS,4);print$2,$4,$6,$8,$10,$12,$14,$16,$18,$20,$22,$24,$26,$28,$30,$32,$34,$36,$38,$40;print substr(OFS,0,3)}'|
while read l;do echo ${l//$1/$2};done|
tee $3
}
```
(Newlines after pipes added for readability.) Working around the restrictions with the shell was fun. I realise there's probably a better way to do `$2,$4,$6,...`, but this was what I came up with anyway.

**Greenway, C#**
53
```
void g(string s,int n){while(n-->0)Console.Write(s);}
```
I decided to swap languages with #1 and #9. Totally worth 30 here for hundreds later.
**Somewhere In The Rough, Python**
59
I really shouldn't have used up such a good language on an easy problem. Also, how is this not part of any language's indexOf family of functions? I seem to always need this...
```
def f(t,s,n):return sum(map(len,t.split(s))[:n+1])+n*len(s)

My bash-foo was never that good to begin with. I'll fiddle with this one later. BTW if you want it to finish faster, switch it over to /dev/urandom.
```
f(){
c=$(($RANDOM%9+9))
for i in $(seq $c);do
echo `tr -cd [:print:]</dev/random|head -c$c`>>$1

}
```
**Treasure Hunt, C**
113 
Probably one of the more C friendly problems. I interpreted "return two integers" as take a return array pointer as an argument. Warnings? What warnings? An int\* is just as good as a FILE\* =p.
```
void f(int*p,int c,int*r){int*f,t;*r=r[1]=0;f=fopen(p,"r");while(c-(t=fgetc(f))){*r=t-'\n'?*r+1:0;r[1]+=*r?0:1;}
```
**Bridge on the River Kwai, Perl**
207
I started learning perl while writing this one. (Better late than never!) I came into this wanting to do regex heroics, so I form the string as both layers of the bridge together, then use regexes with space replacements to form the two different lines.
```
sub f{@trouse=0..$#_-1;foreach $i(@trouse){$r.=sprintf("%d/%+d\\",$_[$i],$_[$i+1]-$_[$i])}$r.=$_[$#_]."\n";print$r=~s/(^|\\)(\d+)(\/|$)/$1.' 'x length($2).$3/egr;print$r=~s/(\/[+-]\d+\\)/' 'x length($1)/egr}
```
**Time Flies When You're Playing Golf, Java**
297
You can only do so much to make java terse... It assumes the clock is space padded so each line is 5 spaces long.
```
public boolean p(int r,int m,String s){int c[]={1,1,0,-1,-1,-1,0,1};return s.charAt(6*c[(r+6)%8]*m+14+c[(r)%8]*m)!=' ';}
public int[]time(String c){int h=9,m=0,t[]={3,5,6,7,9,11,12,1};for(int i=0;i<8;i++)if(p(i,1,c))if(p(i,2,c))m=i;else h=i;if(h==9)h=m;m=(t[m]*5)%60;h=t[h];return new int[]{h,m};}
```
**Timber! Javascript**
201
It runs in chrome's console. I make no guarantees elsewhere =p. It requires that the lines be space padded out to the length of the longest line. I feel like this is a reasonable request of ASCII art.
```
function f(s) {s=s.split("\n")
d={};m={'/':-1,'\\':1};r=1
s.forEach(function(x){t={}
for(i=0;i<x.length;i++){if(x[i]!=' '){j=m[x[i]]?i+m[x[i]]:i

Had fun touching a few languages for a little bit...
Character counts obtained after removing unnecessary spaces/newlines but submission mostly kept readable. Since the question is a mix of functions and programs I included only the body of the function where required... Also some liberty taken with what the meaning of "return" is...
Total **~1719**
1- **Python** (~20)
```
def f(c, n):
    print c*n
```
2- **C** (~109)
```
int f(char*t,char*s,int n){int i;char*q=t;int l=strlen(s);for(i=0;i<n;++i){t=strstr(t, s)+l;}return(t-q-l);}
```
Readable version:
```
#include <string.h>
int f(const char *t, const char *s, int n)
{
  int i;
  char *start = t;
  int l = strlen(s);
  for(i = 0; i < n; ++i)
  {
    t = strstr(t, s) + l;
  }
  return(t - start - l);
}
```
3- **Javascript** (~56)
```
function(x, y) {return function() {for(i=0; i<x(); i++) y();}}
```
4- **Rexx** (~136)
```
f: Procedure
  Parse arg p
  w = random(1, 9)
  h = random(1, 9)
  Do y = 1 to h
    Do x = 1 to w
      Call CHAROUT p, d2c(random(32, 99))
    End
    Call LINEOUT p, ""
  End
```
5- **Scala** (~290)
```
def f(p: String, c: Char) {
  def sc(w: String, c: Char, x: Int, y:Int ): Boolean =
    {
      if(w.isEmpty) false else
      if(w.head==c) {println(x, y); true} else sc(w.tail, c, x+1, y)
    }
  def sr(w: Array[String], c: Char, x: Int, y: Int)
  {
    if(!sc(w.head, c, 0, y)) sr(w.tail, c, 0, y+1)
  }
  sr(io.Source.fromFile(p).mkString.split('\n'), c, 0, 0)
}
```
6- **C++** (~355)
```
void b(list<int> l) // trouser+s
{
  auto i = l.begin();
  auto j = i;
  j++;
  list<int> d;

    }
  }
  cout << o[0].str() << endl << o[1].str() << endl;
}
```
7- **Go** (~301)
Note this requires the clock to be padded (i.e. all lines are same length).
```
func f(p string)(h int,m int) {
  var a=[8]int {0, 2, 4, 12, 16, 24, 26, 28}
  var b=[8]int {7, 8, 9, 13, 15, 19, 20, 21}
  var d=[8]int {11, 12, 1, 9, 3, 7, 6, 5}
  h=9
  c, e := ioutil.ReadFile(p)
  if e==nil {
    for i:=range a {
      if c[a[i]]>32 {
        m=i

    if h==9 {
      h=m
    }
    h=d[h]
    m=d[m]*5%60
  }
  return
}
```
8- **Ruby** (~259)
```
def f(p)
  a,b = File.read(p).split(/\n/).reverse,Hash.new(1)
  a.each_with_index {
    |l,i|
    l.split("").each_with_index {|k,j|
      case k
        when ' '
          b[j] = 0
        when '/'
          b[j] = b[j]|b[j-1]

        if b[j]==0
          return 0
        end
      end
    }
  }
  return 1
end
```
9- **bash/Unix hack** (~193)
```
wget -qO - http://news.ycombinator.com/rss | tr "\074\076" "\n" | grep -B1 /title | awk 'NR % 3 == 1' | head -21 | tail -20 | sed 's/$1/$2/' | awk '{ print "\074h1\076" $0 "\074/h1\076"}' > $3

[Answer]
Only had time to work on 1/2 of these. You seem to want them in the form of a function and not a one liner. So all of these are functions. Testing code below the function. In Perl.
**Greenway:**
```
sub f{print$_[0]x$_[1]}
#test
&f("abc",5);
```
**Rough:**
```
sub f{$i=-1;$n=$_[2];do{$i=index$_[0],$_[1],$i+1;$n--}while($n>0 && $i>-1);print$i+1}
#test
&f("abcefgacefgabcefgabcefgabcefg","cef",4);
```
**Curry:**
```
use Sub::Curried;
curry f($x,$y){$q=0;foreach(1..&$x){$q=&$y};return $q;}
#test
sub fy { return 1;}
sub fx { return 10;}
print&f(\&fx,\&fy);
```
**Spew:**
```
use Crypt::PRNG qw(random_string_from irand);
sub f{open($o,">$_[0]");$m=(irand)%10+1;map{printf $o "%s\n",random_string_from(['A'..'z'],$m)}(1..$m)}
#test
&f('/tmp/t');
```
**Treasure:**
```
sub f{open($i,"<$_[0]");$x=$y=0;@l=<$i>;while($y<=$#l){$x=1+index$l[$#l-$y],$_[1];@a=($x,$y+1)if($x);$y++;}return\@a}
#test
@b=@{&f('/tmp/t','f')};
print join(",",@b);
```
I'll work on 6-9 tomorrow.

Usage:
Once the code is written, input your string, and terminate your string with a ^a (ctr+a), then immediately after, enter your number.
One caveat: the number given must only be from 0-9 (if you wish a larger one, the ascii value-48 of whatever character you input will be used as `n`)

I’m a cheater & I ain’t played all 9 holes … *yet*. Nonetheless, here’s my hole 8, “Timber” solution in Perl (149 char).
One of my coworkers put this up as as a challenge at work. We’ve been having fun with it, especially me, since I have the lowest par solution so far!
Our rules were that it had to be a stand alone script that outputted `true` or `false` followed by a newline to `STDOUT`, and that no “shebang” was OK.
Below is the “minified” solution. I also put up a “[gist](https://gist.github.com/roosto/9bac5ad8bad9441bdee0)” of the same that includes non-“minified” code & (often tortuously long) explanations of the reasoning behind my approach.

First code golf! (Still a work in progress...)
# 1. Greenway
Language: Python 3.2.3  
File size: 23 bytes  
Code:
```
def f(c,n): print(c*n)
```
# 3. Curry for Dinner

Another work in progress here, and I'm at work so I'll head back later.
**Greenway** in Ruby (14 characters, 24 with *#alligator*), call with `f.(c, n)`
```
f=->c,n{p c*n}#alligator
```

**Somewhere in the Rough** in CoffeeScript (38 characters)
```
f=(t,s,n)->t.split(s,n).join(s).length
```

**Curry for Dinner** in JavaScript (54 characters)
```
f=function(x,y){return function(){for(i=x();i--;)y()}}
```

**Spew** in PHP (111 characters)
This requires `short_open_tag` in the PHP configuration file to be enabled. Otherwise the opening delimiter should be `<?php`, the `@` symbols are used to silence `PHP_NOTICE` errors that are thrown for avoiding enclosing `rand` in quotes, and for not explicitly declaring the `$s` variable. This will generate a square grid of ascii characters between 4 and 30 characters on both axis.
```
<? @$r=rand;$x=$r(4,30);for($i=$x*$x;--$i;){@$s.=$i%$x!=0?chr($r(33,126)):"\n";}file_put_contents($argv[1],$s);
```

# 1. Greenway (Python 2: 20)
```
def a(x,n):print x*n
```
Example input: `a("asdf",3)` -> string(`asdfasdfasdf`)
# 2. Somewhere in the Rough (Python 2: 47)
```
def b(t,s,n):return len(s.join(t.split(s)[:n]))
```
Example input: `b("1,2,333,4,5,6",",",3)` -> int(7)
# 3. Curry for Dinner (Javascript: 61)
```
function c(a,b){d=a();return function(){while(d){d--;b()}};};
```
Example input: `function z(){ return 3; }; function y(){ console.log( '1' ) }; myfunc = c(z,y); myfunc();` -> logs `string(1)` to the console... 3 times.
As per the specs, `c` returns a function, and doesn't actually execute that function itself.
# 4. Spew (C++11: 171)
```
#include<fstream>
using namespace std;void d(string f){ofstream o;int i=rand()%10;int j=rand()%10;o.open(f);for(int x=0;x<i;x++){for(int y=0;y<j;y++){o.put(rand()%256);}}}
```
Not actually tested this, but should work.
[Answer]
Some indentation is left intact for readability but it was taken out when counting characters. The total is around ~~1227~~. Or not, I forgot a problem. ~~1486~~ 1465 characters.
**1. MIPS ASM (55 chars)**
```
#a0 : the address of the null terminated string.
#a1 : the repetition count.
f:
li $v0,4
syscall
addi $a1,$a1,-1
bne $a1,$0,f
jr $ra
```
**2. Scheme (52 chars)**
```
(define (f t s n)(list-ref(string-search-all s t)n))
```
**3. F# (39 chars)**
```
let f x y=fun()->for i in 1..x() do y()
```
**4. Powershell (133 chars)** 
```
Function f($p){
$r=(Get-Random)%100
$z="";for($b=$r*$r;$b -gt 0;$b--){$z+=[char](33+(Get-Random)%94);if($b%$r -eq 1){"$z">>$p;$z=""}}
}
```
**5. C++ (~~184~~ 152 chars)**
```
#include <istream>
#include <string>
int*f(std::string p,char c){int*x=new int[2]();std::ifstream i(p);for(;i>>p;x[1]++)if((x[0]=p.find(c))>0)return x;}
```
**6. C# (~~291~~ 282 chars)**
```
static void f(List<int> l)
{
    var z = "";
    var o = l[0].ToString();
    for (int j = 1; j < l.Count;j++)
    {
        int p = l[j-1];
        int i = l[j];
        var q = "/"+(i-p<0?"":"+")+(i-p).ToString()+"\\";
        o += new String(' ',q.Length)+i.ToString();
        z+=new String(' ',p.ToString().Length)+q;
    }
    Console.Out.Write(z+"\n"+o);
}
```
**7. Haskell (~~318~~ 306 chars)**
I was looking for an excuse to try out Haskell. I thought I was clever by generating the list of positions via combinations of numbers, but with the number of characters it took I could have hard coded the damn thing. Oh well. The code is atrocious but it was fun to write anyway.
edit: Fixed so it correctly returns minutes.
```
w i s=[s!!(j!!1)!!(j!!0)/=' '|j<-mapM(const i)[1,2],j/=[2,2]]
k[e,r](i,o,n)|i&&o=[e, n]|i&&not o=[n, r]|not$o||i=[e, r]
g s=let[h,m]=foldl k[0,0](zipWith3(\x y z->(x,y,z))(w[1,2,3]s)(w[0,2,4]s)[11,9,7,12,6,1,3,5])in let u=mod(m*5)60 in if h==0 then[m,u]else[h,u]
f p = do
  s<-readFile p
  return$g$lines s
```
**8. Lua (259 chars)**
I was surprised to find that strings didn't support array style indexing, so I had to rely on sub.
```
function f (p)
    s=' ' g=''
    for l in io.open(p):lines() do l=l..s:rep(#g-#l) for v=1,#g do
        d=({['/']=v-1,['\\']=v+1,[s]=0})[g:sub(v,v)] or -1
        if l:sub(v,v)==s and (d<0 or d>0 and g:sub(d,d)==s and l:sub(d,d)==s) then
            return false
        end
    end g=l end
    return true
end
```
