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*)
s = list(map(int, input().split(' ')))
ar = []
if s[1] - s[2] > 1:
    ar.append('<<')
    for i in range(0, s[2]):
        ar.append(s[1]-s[2]+i)
    ar.append('({})'.format(s[1]))
    if s[0]-s[1] > s[2]:
        for i in range(0, s[2]):
            ar.append(s[1]+i+1)
        ar.append(('>>'))
    else:
        for i in range(0, s[0] - s[1]):
            ar.append(s[1]+i+1)
elif s[1] - s[2] == 1:
    for i in range(0, s[2]):
        ar.append(s[1]-s[2]+i)
    ar.append('({})'.format(s[1]))
    if s[0]-s[1] > s[2]:
