3 Sum Optimal Solution | Two Pointer Approach Explained

In this video, we solve the 3 Sum problem using the optimal approach ⚡

Instead of using brute force, we use:

Sorting + Two Pointer technique
Time Complexity: O(n²)
Efficient way to avoid duplicate triplets
🔍 Key Idea:
First, sort the array
Fix one element
Use two pointers (left & right) to find remaining two numbers
Skip duplicates to get unique triplets

This approach is widely used in coding interviews and is a must-know optimization technique 🚀
