The Logical Approach: Solve LeetCode 724 Find Pivot Index in Java

In this video, we dive into LeetCode 724: Find Pivot Index. We explore how to find the "equilibrium" point of an array where the sum of elements on the left equals the sum of elements on the right. I’ll walk you through the Java logic using a suffix-sum array approach to solve it efficiently! 🔗 Problem Link: https://leetcode.com/problems/find-pi... 🚀 Complexity Analysis: •Time Complexity: O(n) •We traverse the array twice: once to build the rightSum array and once to find the pivot. Since these are linear passes, the time grows proportionally with the input size. •Space Complexity: O(n) •We utilize an auxiliary integer array rightSum of size $n$ to store the suffix sums, which requires linear extra memory. #LeetCode #Java #CodingInterview #DataStructures #Algorithms #Programming
