Given an array of unique elements, find all the possible permutations. This video shows how to identify the logic which creates all different permutations. Once we know how to find permutations, we can map it to the backtracking algorithmic paradigm. The concept is super simplified using diagrams and visuals of state space tree. You will also find a dry-run of the code in JAVA. • The actual problem on LeetCode: https://leetcode.com/problems/permuta... • Chapters: • 00:00 - Intro • 01:13 - Understanding the problem • 02:51 - Logic to find permutations • 06:43 - Using Backtracking to find permutations • 11:52 - Dry-run of Code • 15:36 - Final Thoughts • 📚 Links to topics I talk about in the video: • Brute Force Paradigm: • Brute Force algorithms with real life... • Backtracking: • Backtracking made easy | Algorithmic ... • Similar problem (Subsets): • Subsets (LeetCode 78) | Full solution... • Other problems on LeetCode: • Leetcode Solutions • 📘 A text based explanation is available at: https://studyalgorithms.com • Code on Github: https://github.com/nikoo28/java-solut... • Test-cases on Github: https://github.com/nikoo28/java-solut... • 📖 Reference Books: • Starting Learn to Code: https://amzn.to/36pU0JO • Favorite book to understand algorithms: https://amzn.to/39w3YLS • Favorite book for data structures: https://amzn.to/3oAVBTk • Get started for interview preparation: https://amzn.to/39ysbkJ • 🎥 My Recording Gear: • Recording Light: https://amzn.to/3pAqh8O • Microphone: https://amzn.to/2MCX7qU • Recording Camera: https://amzn.to/3alg9Ky • Tablet to sketch and draw: https://amzn.to/3pM6Bi4 • Surface Pen: https://amzn.to/3pv6tTs • Laptop to edit videos: https://amzn.to/2LYpMqn • • 💻 Get Social 💻 • Follow on Facebook at: / studyalgos • Follow on Twitter at: / studyalgorithms • Follow on Tumblr at: / studyalgos • Subscribe to RSS feeds: https://studyalgorithms.com/feed/ • Join fan mail: http://eepurl.com/g9Dadv • #leetcode #backtracking #interview
