String diversity is the number of symbols that occur in the string at least once. Diversity of *s* will be denoted by *d*(*s*). For example , *d*("aaa")=1, *d*("abacaba")=3.

Given a string *s*, consisting of lowercase Latin letters. Consider all its substrings. Obviously, any substring diversity is a number from 1 to *d*(*s*). Find statistics about substrings diversity: for each *k* from 1 to *d*(*s*), find how many substrings of *s* has a diversity of exactly *k*.
The input consists of a single line containing *s*. It contains only lowercase Latin letters, the length of *s* is from 1 to 3·10<sup class="upper-index">5</sup>.
s = input()

dist = set(s)
print(len(dist))

resDict = dict()
for i in range(len(s)):
    for j in range(i + 1, len(s) + 1):
        curDist = len(set(s[i:j]))
        if curDist in resDict:
            resDict[curDist] += 1
        else:
            resDict[curDist] = 1
