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*)
t = 1#int(input())

for tt in range(t):
    n,p,k = map(int,input().split())
    start = p - k
    if start <= 0:
        start = 1
        
    if start > 1:
        print('<<',end = ' ')
        
    for i in range(start,p):
        print(i,end = ' ')

    end = p + k
    if end > n:
        end = n
    print('({0})'.format(p),end = ' ')
    for i in range(p+1,end+1):
        print(i,end = ' ')
        
    if end != n:
        print('>>',end = ' ')
    print('')
