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*)
def function(n, p, k):
    builder = ''
    if p-k > 1:
        builder += '<< '
    if p-k > 0:
        start = p-k
    else:
        start = 1
    if p+k >= n:
        end = n+1
    else:
        end = p+k+1
    for i in range(start,end):
        if i == p:
            builder += '('+str(i)+') '
        else:
            builder += str(i) + ' '
    if p+k < n:
        builder += '>>'
    return builder

def main():
    inp = list(map(int, input().strip().split()))
    out = function(*inp)
    print(out.strip())
