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*)
ins = input()

inputs = ins.split(" ")

n = int(inputs[0])
p = int(inputs[1])
k = int(inputs[2])

string = ""

if p - k <= 1:
	l = 1
else:
	l = p - k

if p + k >= n:
	r = n
else:
	r = p + k

if l != 1:
	string = string + "<< "

for i in range(l,r + 1,1):
	if i == p:
		string = string + "(" + str(i) + ") "
	elif i == r:
		string = string + str(i)
	else:
		string = string + str(i) + " "

if r != n:
	string = string + " >>"

print(string)
