🔍 Leetcode 242: Valid Anagram - Array & HashMap Approaches Explained! 🔍
🚀 In this video, we solve the Valid Anagram problem from Leetcode (#242) using two efficient approaches:
✅ Array Approach (Optimized for English Letters):
1️⃣ Create an array of size 26 (since input contains only lowercase English letters).
2️⃣ Iterate through both strings, incrementing for s and decrementing for t.
3️⃣ If the array remains all zeros, the strings are anagrams.
✅ HashMap Approach (Follow-up for Unicode Characters):
1️⃣ Use a HashMap to store character frequencies from s.
2️⃣ Decrease the frequency for each character in t.
3️⃣ If all values are zero, return true, otherwise false.
