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())

if p==1:
    if p+k<=n:
        print('(1)',end =" ")
        for i in range (1,k+1):
            print(i+1,end =" ")
        if (p+k < n):
            print('>>')    
    else:
        print('(1)',end =" ")
        for i in range (1,n+1):
            print(i+1,end =" ")
elif p ==n:
    if (p-k > 1):
            print('<<')  
    for i in range (p-k,p):
            print(i,end =" ")
    print('(',n,')',sep ="")        
else:
    if (p-k > 1):
            print('<<',end =" ")  
    for i in range (p-k,p):
            if (i >= 1):
                print(i,end =" ")  
    print('(',p,')',sep ="",end =" ")   
    for i in range (p,p+k):
            if (i+1<=n):
                print(i+1,end =" ")  
    if (p+k < n):
            print('>>')
