/**
 * Day 5 — Valid Anagram
 * 
 * Given two strings s and t, return true if t is an anagram of s, and false otherwise.
 * An anagram uses exactly the same characters with the same frequencies.
 * 
 * Examples:
 *   isAnagram("anagram", "nagaram") → true
 *   isAnagram("rat", "car") → false
 * 
 * Constraints:
 *   - 1 <= s.length, t.length <= 5 * 10^4
 *   - s and t consist of lowercase English letters
