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())
out = []
if p==1 and p+k<n:
    out.append('(1)')
    for i in range(1,k+1):
        out.append(str(1+i))
    out.append(">>")

elif p==1 and p+k>=n:
    out.append("(1)")
    for i in range(1,n):
        out.append(str(i+1))

    out.append('<<')
    for i in range(k,0,-1):
        out.append(str(n-i))
    out.append('('+str(n)+')')

elif p==n and p-k<=1:
    for i in range(1,n):
        out.append(str(i))
    out.append('('+str(n)+')')
