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*)

    prefix = (" ".join([str(i) for i in range(1,current)])).rstrip()
else:
    prefix = ("<< " +" ".join([str(i) for i in range(start,current)])).rstrip()
if end >= pages:
    suffix = (" ".join([str(i) for i in range(current+1,pages+1)])).rstrip()
else:
    suffix = (" ".join([str(i) for i in range(current+1,end+1)])+" >>").rstrip()
if prefix == '' and suffix=='':
    print(mid)
elif prefix == '':
    print(mid,suffix)
elif suffix == '':
    print(prefix,mid)
else:
    print(prefix,mid,suffix)
