Consider a string s of length n consisting of characters 0 to 9. Let \(r(s)\) be the number of distinct characters this string has, and \(N(c)\) be the number of times character c appears in the string. We call the string s happy if \(N(0) \lt \frac{n}{r(s)} \)
For example strings \(010\) and \(012\) are NOT happy, but strings \(0112\) and \(123456789\) are happy.
Given a string S, find the number of happy substrings(out of a total \(\frac{|S|(|S|+1)}{2} \) ) of S.
Input
The only line of the input contains the string S
Output
Print one line containing the number of happy substrings of S
