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=input()
p=input()
k=input()

a = ""
if n>p - k > 1:
    l1 = p - k
    a += "<<"
elif p - k <= 1:
    l1 = 1
if p + k < n:
    l2 = p + k+1
    s = " >>"
elif p + k >= n:
    l2 = n+1
    s = ""

for i in range(l1, l2):
    if i == p:
        a += ' (' + str(p) + ')'
    elif i!=p:
        a+=' '+str(i)
a+=s
print(a.strip())
