Squares of Sorted Array (LeetCode 977) | Full Solution with examples & animation | Study Algorithms
Usually we iterate through an array from the forward direction or the backward direction. Often we neglect the fact that we can also iterate the array from both the directions simultaneously. Watch this video to see how we can find the squares of a sorted array efficiently using two pointers head and tail. All along with animations and a dry-run of code in JAVA.
