Read MoreSubstring with maximum ASCII sum when some ASCII values are redefined
In this problem, we will find the substring of the given string whose character's ASCII value's sum is maximum when we redefine the ASCII values. The naïve approach to solve the problem is to find the sum of all substring's character's ASCII value and get the substring having maximum sum. Another approach to solving the problem is using Kadane's algorithm to find the maximum sub-array sum. Problem statement - We have given a string alpha of size N containing the alphabetical characters. We have also given the chars[], and ASCII[] array of size M, where chars[] contains ...
