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 solve(n, c, off):
    ans = '({})'.format(c)

    # go right
    tem_off = off
    counter = c+1
    while tem_off and counter <= n:
        ans += ' {}'.format(counter)
        counter += 1
        tem_off -= 1
    if n-c > off:
        ans += ' >>'
    
    # go left
    tem_off = off
    counter = c-1
    while tem_off and counter >= 1:
        ans = '{} '.format(counter) + ans
        counter -= 1
        tem_off -= 1

    if c-1 > off: ans = '<< ' + ans
    return ans
