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*)
Max,This,Range = map(int, input().split(' '))

Result = ''

MinRange = This - Range

if This - Range > 1:
    Result += '<< '
else:
    MinRange = 1 

MaxRange = This + Range

if This + Range > Max:
    MaxRange = Max

MinMaxRange = This - 1
MaxMinRange = This + 1

if MinMaxRange >= MinRange:
    for i in range(MinRange,MinMaxRange+1):
        Result += str(i) + ' '

Result += '(' + str(This) + ')'

if MaxMinRange <= MaxRange:
    Result += ' '
    for i in range(MaxMinRange,MaxRange+1):
        Result += str(i) + ' '
    Result = Result[:-1]

if This + Range < Max:
    Result += ' >>'

print(Result)
