Hash-Based Algorithms for String and Array Problems

1. Valid Anagram Given two strings s and t, determine if they are anagrams — i.e., contain the exact same characters with the same frequencies. Since characters are constrained to lowercase English letters, a fixed-size integer array of length 26 suffices for counting frequencies. public boolean checkAnagram(String text1, String text2) { i ...
