🧠 Problem Statement

Given two strings s and t, return true if t is an anagram of s, otherwise return false.

Two strings are anagrams if they contain the same characters with the same frequencies.

Example:

Input:

s = "anagram"
t = "nagaram"

Output:

true

━━━━━━━━━━━━━━━━━━━━━━━

⚡ Approach

1️⃣ Store character frequencies from the first string

2️⃣ Decrease frequencies using the second string

3️⃣ Check every character frequency

4️⃣ If any frequency is not zero, return false

5️⃣ Otherwise return true
