This is the 8th Video on our Backtracking Playlist.
In this video we will try to solve a classic Backtracking Problem Permutations - (Leetcode 46).
Share your learnings on LinkedIn, Twitter (X), Instagram, Facebook(Meta) with hashtag hashtag #codestorywithmik & feel free to tag me.
Trust me, this will no longer be a Medium Problem. I will explain the intuition so easily that you will never forget and start seeing this as cakewalk EASYYY.
We will do live coding after explanation and see if we are able to pass all the test cases.
