Solution (in PYTHON):

Solution:
def ans(inp):
    s = tuple(inp)
    SubstringArray=[]
    for length in range(1, len(s)+1):
        for index in range(len(s)+1-length):
            SubstringArray.append(inp[index:index+length])
    return SubstringArray
x=raw_input()
danger=set(ans(x))
print len(danger)
