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=input().split()
n,p,k=int(n),int(p),int(k)
x=p-k
y=p+k
f=0
h=0
if x<=1:
	x=1
	f=1
if y>=n:
	y=n
	h=1
lst=[]
for i in range(x,y+1):
	if i==p:
		lst.append('('+str(p)+')')
	else:
		lst.append(str(i))

if f==1 and h==0:
	print(' '.join(lst),'>>')
elif f==0 and h==1:
	print('<<',' '.join(lst))
elif f==1 and h==1:
	print(' '.join(lst))
else:
	print('<<',' '.join(lst),'>>')
