Recursion and Backtracking Course

Master recursion and backtracking through this comprehensive 11-hour 50-minute course that progresses from fundamental concepts to advanced problem-solving techniques. Begin with recursion basics and gradually advance through level 1 questions, array manipulations, and pattern problems including bubble sort and selection sort implementations. Explore essential sorting algorithms like merge sort and quick sort with detailed complexity analysis and recursive implementations. Dive into advanced topics including subsets, subsequences, string problems, and permutation generation with theoretical foundations and practical coding examples. Learn to tackle challenging interview questions from Google and Amazon, including dice throw problems and letter combinations of phone numbers. Progress to backtracking concepts through maze problem solving, then apply these skills to complex algorithmic challenges including N-Queens, N-Knights, and Sudoku solver problems from LeetCode. Each section combines theoretical understanding with hands-on coding practice and valuable tips for mastering these crucial computer science concepts essential for technical interviews and competitive programming.
