Valid Anagram
Given two strings s and t Return true if t is an anagram of s, false otherwise An anagram uses the same characters with the same frequencies Example: s = "anagram", t = "nagaram" => true Example: s = "rat", t = "car" => false
Are these two strings made of the exact same letters? It's a simple question that tests whether you can count efficiently. Most candidates reach for sorting, but interviewers are watching to see if you think about character frequency instead. Nail this pattern and you'll breeze through the harder string-matching problems.
