Quick Sort Dry Run in 30 Seconds πŸ”₯ | CodeArc Most people memorize Quick Sort but never actually understand how the partition works. Watch this step by step dry run and see exactly how the pivot, i pointer, and j pointer work together to sort the array. We pick the last element as pivot. j scans the array. Whenever arr j is smaller than pivot, i increments and we swap. At the end pivot goes to its correct position. Then we recurse on both halves. Time Complexity β€” O n log n average, O n squared worst case Space Complexity β€” O log n recursion stack Save this for your DSA revision.

Most Developers Choose the Wrong Algorithm! Algorithms are the foundation of efficient programming. Learning algorithms helps developers solve problems faster and choose the best solution for different situations. Understanding search algorithms like Linear Search and Binary Search is important for writing optimized programs. In programming, different problems require different algorithms. For example, if the data is unsorted we can use Linear Search, but if the data is sorted Binary Search is much faster. Learning algorithms helps developers understand which algorithm to use for which problem. What we will learn in this video β€’ Why programmers must learn algorithms β€’ Difference between Linear Search and Binary Search β€’ How choosing the right algorithm improves performance β€’ How algorithms help write efficient programs Who this video is for β€’ Beginners learning programming and computer science β€’ Students preparing for DSA and coding interviews β€’ Developers who want to understand efficient algorithms ⬇️ Watch the full DSA tutorial here πŸ“š DSA with Java | Zero to One (Hinglish): https://www.youtube.com/playlist?list=PLetIznSWv_ZojkWOOEixCUdU2cAdclmn6 #algorithm #algorithms #dsa #programming #coding
