Most of the string based problems either revolve around a prefix or a suffix. A prefix is a character or a sequence of characters that occur in the beginning of a string. In this problem we try to find the longest common prefix in an array of strings. studyalgorithms.com/string/leetcod…

[Hackerrank] - Making Anagrams Solution Given two strings, determine the total number of characters to be deleted such that they become anagrams. We use counting sort to create buckets of each character frequency to derive an optimal solution. studyalgorithms.com/string/hackerr…

Given an array of strings strs, you need to group all the anagrams together. You can return the answer in any order. You can either group by sorting the characters or by frequency. The latter gives you a better time complexity. studyalgorithms.com/string/leetcod…
