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*)
def pr(x,n,p):
    s=''
    if x[0]!=1:
        s+='<< '
    for i in range(len(x)):
        if x[i]==p:
            s+='('+str(x[i])+') '
        else:    
            s+=str(x[i])
            s+=' '
    if x[len(x)-1]!=n:
        s+='>>'
    print(s)



# x[0]=n, x[1]=p, x[2]=k
x=[int(x) for x in input().split()]
l=[x[1]]

for i in range(1,x[2]+1):
    a = x[1]+i
    b = x[1]-i
    if a<=x[0]:
        l.append(a)
    if b>0:
        l.insert(0,b)
pr(l,x[0],x[1])
