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,p,k=map(int,input().split())
a=[]
if(p>k):
	for i in range(2*k+1):
		if((p-k+i)>n):
			break
		a.append(p-k+i)
elif(p<=k):
	for i in range(1,p):
		a.append(i)
	a.append(p)
	for i in range(k):
		if((p+i+1)>n):
			break
		a.append(p+i+1)
s=""
if(a[0]!=1):
	s+="<< "
for i in a:
	if(i==p):
		s+="("+str(i)+")"+" "
	else:
		s+=str(i)+" "
if(a[len(a)-1]!=n):
	s+=">>"
print(s.strip())
