Longest Resilient Subarray I & II | Brute Force to Optimal | O(N³) to O(N) | C++

Longest Resilient Subarray I & II | LeetCode Biweekly Contest 193 Problem Link : https://leetcode.com/contest/biweekly... Source Code : https://github.com/Krishnkantm/DSA-Co... In this video, we solve Longest Resilient Subarray and discuss three approaches, from brute force to an optimized solution. Approaches Covered: Brute Force: Check all possible subarrays and validate the resilient condition. Better Approach: Optimize subarray sum calculations using prefix sums. Optimal Approach: Use an O(N) technique to find the longest valid resilient subarray. We discuss the key observation, dry runs, and time and space complexity of each approach. Time Complexity: Brute Force: O(N³) Better Approach: O(N²) Optimal Approach: O(N) Topics: Prefix Sum, Subarrays, Array Problems, Optimization, Brute Force, DSA, LeetCode Contest Subscribe to Logic Mode for LeetCode, GFG and DSA solutions in C++.
