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 ...
