Rotate Array: https://leetcode.com/problems/rotate-array/ ⭐ Support my channel and connect with me: https://www.youtube.com/channel/UCPL5uAbYQ40HwAdOe4ikI0w/join Solutions explained: Solution1: we could use a nested for loop, rotate every single element to the right one at a time, total k times, this could potential results in TLE (Time Limit Exceeded exception on LeetCode OJ), time complexity: O(n*k), space complexity: O(1); Solution 2: we could trade off space for time: use an extra array to help, assign all elements into its final correct position in the extra array, then copy the extra array into the input array. Time: O(n), Space: O(n); Solution 3: we could reverse the input array three times: 1. first reverse this entire array, 2. secondly, reverse the array from 0 to k - 1 3. lastly, reverse the array from k to length - 1 Time: O(n), Space: O(1) // TOOLS THAT I USE: ○ Memory Foam Set Keyboard Wrist Rest Pad - https://amzn.to/3cOGOAj ○ Electric Height Adjustable Standing Desk - https://amzn.to/2S9YexJ ○ Apple Magic Keyboard (Wireless, Rechargable) - https://amzn.to/36gy5FJ ○ Apple Magic Trackpad 2 (Wireless, Rechargable) - https://amzn.to/36ltimu ○ Apple MacBook Pro - https://amzn.to/30iSvKE ○ All-In One Printer - https://amzn.to/34etmSi ○ Apple AirPods Pro - https://amzn.to/2GpVYQf ○ My new favorite Apple Watch - https://amzn.to/2EIIUFd // MY FAVORITE BOOKS: ○ Introduction to Algorithms - https://amzn.to/36hxHXD ○ Designing Data-Intensive Applications - https://amzn.to/2S7snOg ○ Head First Java - https://amzn.to/2ScLDKa ○ Design Patterns - https://amzn.to/2SaGeU2 Follow me on Github for complete LeetCode solutions: https://github.com/fishercoder1534/Leetcode Support me on Patreon: https://www.patreon.com/fishercoder My ENTIRE Programming Equipment and Computer Science Bookshelf: https://www.amazon.com/shop/fishercoder And make sure you subscribe to my channel! #softwareengineering #leetcode #algorithms #coding #interview #SDE #SWE #SiliconValley #programming #datastructures Your comments/thoughts/questions/advice will be greatly appreciated!
