Скачать или смотреть Longest Subarray Length | GFG POTD | Stack | Full Explanation

In this video, we solve the GeeksforGeeks Problem of the Day (POTD) – Longest Subarray Length.

We start with an example, then cover the brute force approach, write pseudocode, and move on to the optimized solution using Next Greater Element (NGE) and Previous Greater Element (PGE) stack-based techniques.
Finally, we analyze the time & space complexity and write the complete code.

This problem is a standard stack application (NGE & PGE), and solving it will strengthen your array + stack concepts which are commonly asked in interviews and DSA contests.
