Leetcode 724. Find Pivot Index Explained | Java | Pattern 1 : Array Traversal & Simulation

In this video, we solve the coding interview problem *Find Pivot Index (LeetCode 724)* using Java. The pivot index is the position in an array where the sum of elements on the left is equal to the sum of elements on the right. In this tutorial, we explain: • Brute Force approach to check each index • Optimal solution using the Total Sum method • Array traversal technique • Time and Space Complexity analysis • Clean Java implementation We demonstrate how calculating the total sum of the array allows us to compute the right sum instantly using the formula: rightSum = totalSum - leftSum - nums[I] This reduces the complexity from **O(n²) to O(n)**. Topics covered: • Data Structures and Algorithms (DSA) • Array Traversal • Prefix Sum Logic • Coding Interview Preparation • Java DSA Problem Solving This video is part of the *Top 20 DSA Patterns for Coding Interviews in Java* playlist where we solve **100+ real coding interview questions step-by-step**.
