Two Pointer Approach | Pair with Given Difference | DSA in Java Lecture 3

In this video, we solve an important Two Pointer problem in DSA using Java. 👉 Problem Statement: We are given a sorted integer array Arr[N] and an integer diff. We need to determine whether there exists a pair (i, j) such that: i ≠ j Arr[i] - Arr[j] = diff If such a pair exists, return true, otherwise return false. 🚀 What You’ll Learn: Two Pointer Approach Explained How to solve problems on sorted arrays Optimized solution (O(N)) Step-by-step dry run Clean Java code
