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 main():
    n,p,k = map(int ,input().split())
    if p - k < 1:
        r = range(1, p)
    else:
        r = range(p-k,p)
    if p - k - 1 >= 1:
        pn('<< ')
    for i in r:
        pn(str(i) + ' ')
    pn('('+str(p)+')')
    if p + k > n:
        r = range(p+1, n+1)
    else:
        r = range(p+1,p+k+1)
    for i in r:
        pn(' ' + str(i))
    if p + k + 1 <= n:
        pn(' >>')
    pn('\n')
