Next Permutation | Brute Force → Optimal Approach | In-Place Algorithm | StackedUp

In this video, we break down the popular LeetCode problem Next Permutation and understand how to compute the next lexicographically greater permutation using an optimal in-place approach. We’ll cover: • What “next permutation” really means (intuition first) • Brute force idea using all permutations (and why it’s inefficient) • Step-by-step optimal in-place algorithm (interview trick) • Finding the breakpoint, swapping, and reversing logic • Dry run on sample inputs for clarity • Time & space complexity explanation This is a must-know problem for coding interviews as it teaches array manipulation, pattern observation, and in-place optimization techniques. Perfect for: • DSA preparation • Coding interviews • LeetCode practice • Strengthening problem-solving intuition If you found this helpful, make sure to like, share, and subscribe to StackedUp for more DSA explanations from basics to advanced. #leetcode #dsa #arrays #codinginterview #permutations #stackedup
