( 5719 ) B Choosing Symbol Pairs PROGRAMMING strings 1500

B'There is a given string S consisting of N symbols. Your task is to find the number of ordered pairs of integers i and j such that 1. 1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89i, xe2 x80 x89j xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89N 2. S[i] xe2 x80 x89= xe2 x80 x89S[j], that is the i-th symbol of string S is equal to the j-th. The single input line contains S, consisting of lowercase Latin letters and digits. It is guaranteed that string S in not empty and its length does not exceed 105. Print a single number which represents the number of pairs i and j with the needed property. Pairs (x, xe2 x80 x89y) and (y, xe2 x80 x89x) should be considered different, i.e. the ordered pairs count.'...
