01. Remove Element β LeetCode | 2 Powerful Approaches Explained π₯ (Two Pointers + Overwrite)
Notes
In this video, we solve the "Remove Element" problem from LeetCode using two simple and efficient approaches:
- Two-pointer swap technique β works well when the element to remove is scattered.
- Overwrite method β clean and reliable, great for all scenarios.
Both approaches run in O(n) time, use O(1) space, and modify the array in-place β exactly what interviewers expect.
