# Solution for Codeforces problem 757A. from collections import defaultdict import time from functools import partial """ We need to normalize the dictionary b/c there are repeating letters. How can this normalization be done? The number of letter repeatance can be found for each repeating letter. Then that number can be used to divide total count of the repeating letter. This means a dictionary must contain two things: count and number of repeat. Or there must be two dictionaries. I prefer a single dictinoary. Another solution might be having a single dictinoary that contains the letter as the key and a function as the value. Can you make a function that counts on a given number? (e.g. calling func(3) three times would result to 1, 6 times results to 2.
