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*)
inputs = input().split(" ")
ran,base,limit = int(inputs[0]),int(inputs[1]),int(inputs[2])
if((base - limit) > 0):
    start = base - limit
else:
    start = 1
if((base + limit) > ran):
    finish = ran + 1
else:
    finish = base + limit +1
output = ""
if(start is not base):
    output+="<<"
for i in range(start, finish):
    if(i  == base):
        output+="("+str(base)+")"        
    else:
        output+=str(i)
if(ran > (finish-1)):
    output+=">>"
print(output)
#print(inputs, len(inputs))
