User ainta is making a web site. This time he is going to make a navigation of the pages. In his site, there are *n* pages numbered by integers from 1 to *n*. Assume that somebody is on the *p*-th page now. The navigation will look like this:

When someone clicks the button "&lt;&lt;" he is redirected to page 1, and when someone clicks the button "&gt;&gt;" he is redirected to page *n*. Of course if someone clicks on a number, he is redirected to the corresponding page.

There are some conditions in the navigation:
 -  If page 1 is in the navigation, the button "&lt;&lt;" must not be printed. -  If page *n* is in the navigation, the button "&gt;&gt;" must not be printed. -  If the page number is smaller than 1 or greater than *n*, it must not be printed. 
You can see some examples of the navigations. Make a program that prints the navigation.
The first and the only line contains three integers *n*, *p*, *k* (3 ≤ *n* ≤ 100; 1 ≤ *p* ≤ *n*; 1 ≤ *k* ≤ *n*)
n,p,k=map(int,input().split())
a=""
sum=0

if(p-k!=1 and p-k>0):
    a=a+"<<"
i=0
while(sum!=p):
    r=p+i-k
    sum=r
    i=i+1
    if(sum<1):
        continue
    if(sum==p):
        a=a+" "+"("+str(p)+")"
        break
    else:
        a=a+" "+str(sum)
i=i-2
while(sum!=p+k):
    sum=p+k-i
    i=i-1
    a=a+" "+str(sum)
    if(sum==n):
        break
if(p+k<n):
    a=a+" "+">>"
print(a)
