42_A. Guilty — to the kitchen!_1900
It's a very unfortunate day for Volodya today. He got bad mark in algebra and was therefore forced to do some work in the kitchen, namely to cook borscht (traditional Russian soup). This should also improve his algebra skills. According to the borscht recipe it consists of n ingredients that have to be mixed in propor...

451_D. Count Good Substrings_1902
We call a string good, if after merging all the consecutive equal characters, the resulting string is palindrome. For example, "aabba" is good, because after the merging step it will become "aba". Given a string, you have to find two values: 1. the number of good substrings of even length; 2. the number of good ...

A string is a primeString if the number of distinct alphabets used in the string is a prime and also the number of occurrences of each alphabet in the string is also a prime. Given a String you need to tell if it is a primeString or not. Input: First line contains T which is t...
