In this problem, we will construct two palindromic strings using the given string’s characters. We can use the character’s frequency to solve the problem. We can construct two new palindromic strings only if both characters’ frequencies are even or if any characters have an even frequency and others have an odd frequency. Problem statement − We have given a string alpha containing two different characters and a size equal to N. We need to construct two palindromic strings using the characters of the alpha, which are not the same as the given string alpha. Sample Examples After incrementing each character ...
