Problem: You are given a string S. Find the number of different substrings in S.

Input
One line containing a string S consisting of lowercase Latin letters.

Output
Output one integer - answer to the question.

Constraints
1 ≤ length of S ≤ 1200

SAMPLE INPUT
abc

SAMPLE OUTPUT

Solution (in PYTHON):

Solution:
'''
# Read input from stdin and provide input before running code

name = raw_input('What is your name?\n')
print 'Hi, %s.' % name
'''
#print 'Hello World!'

def consecutive_groups(iterable):
    s = tuple(iterable)
    for size in range(1, len(s)+1):
        for index in range(len(s)+1-size):
            yield iterable[index:index+size]
n =raw_input()
b =list(consecutive_groups(n))
b= set(b)
print len(b)
