Day 11 ✅ 🔹Completed the sort an array problem using merge sort algorithm 🔹Merge sort uses divide & conquer technique, in which we first break the array into smaller chunks & while backtracking we sort & then merge it. #DSA #BuildingABetterVersionOfMe #LeetCode 🔥🔥

Day 10 ✅ 🔹Solved the knights tour problem, didn't get it in one go, have to watch the yt lec but yeah now gotcha 🔹TC is O(8^n^2) coz we're having 8 choices at every n*n grid & SC is O(n^2) coz of the call stack #DSA #letsconnect #BuildingABetterVersionOfMe #LeetCode 🔥🔥🔥

Day 9✅ 🔹Did the count inversion problem, the brute force is simple but the optimized one is based on merge sort concept 🔹Also learnt the quick sort algorithm, which is an in place algorithm with O(nlogn) time complexity (O(n^2) in the worst case) & constant space complexity 🔥
