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*)
pn, cp, t = map(int, input().split()) 
my_str =[]
out=[]
for i in range(pn):
    if i ==cp-1:
        my_str.append(f"({i+1}) ")
    else:    
        my_str.append(f"{i+1} " )
   
index=cp-1 
l_index=index-t  
r_index=index+t+1 
if l_index<0 :
    l_index=0
if r_index >len(my_str):    
      r_index=len(my_str)+1
out=my_str[l_index:r_index]

if l_index > 0 and r_index < len(my_str):
    print("<<",end=" ")
    for i in out:
        print(i,end="")
    print(">>",end="")    
elif  l_index<=0 and r_index < len(my_str):
     for i in out:
        print(i,end="")
     print(">>",end="")
elif  l_index<0 and r_index >= len(my_str):
        print("<<",end=" ")
        for i in out:
          print(i,end="")
else:
         for i in out:
          print(i,end="")
