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*)
n, p, k = input().split()
n, p, k = int(n), int(p), int(k)

l = []

if (p-k)>1 and (p+k)<n:
    l.append('<<')
    for i in range((p-k),p):
        l.append(i)
    l.append('('+str(p)+')')
    for i in range((p+1),(p+k+1)):
        l.append(i)
    l.append('>>')
elif (p-k)<=1 and (p+k)<n:
    for i in range(1, p):
        l.append(i)
    l.append('('+str(p)+')')
    for i in range((p+1), (p+k+1)):
        l.append(i)
    l.append('>>')
elif (p-k)>1 and (p+k)>=n:
    l.append('<<')
    for i in range((p-k), p):
        l.append(i)
    l.append('('+str(p)+')')
    for i in range((p+1),(n+1)):
        l.append(i)
else:
    for i in range(1, p):
        l.append(i)
    l.append('('+str(p)+')')
    for i in range((p+1),(n+1)):
        l.append(i)
print(*l)
