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*)
strI = input().split(' ')

n, p, k = [int(i) for i in strI]

i = 1
end = p+k

ch1 = p-k
ch2 = p+k

if ch2 >= n:
    ch2 = n

if ch1 <= 1:
    i = 1
else:
    i = ch1

out = ''

while i <= ch2:

    if i == 1 and p == 1:
        out += '(' + str(i) + ') '
    elif i == 1:
        out += str(i) + ' '
    elif i == ch1 and p == ch1:
        out += '<< (' + str(i) + ') '
    elif i == ch1:
        out += '<< ' + str(i) + ' '
    elif i == n and p == n:
        out += '(' + str(i) + ') '
    elif i == n:
        out += str(i) + ' '
    elif i == ch2 and p == ch2:
        out += '(' + str(i) + ') >>'
    elif i == ch2:
        out += str(i) + ' >>'
    elif i == p:
        out += '(' + str(i) + ') '
    else:
        out += str(i) + ' '

    i += 1

print(out)
