Daily Temperatures in Tamil | Leetcode 739 | Monotonic Stack | NeetCode in Tamil

In this video, we solve the Daily Temperatures problem (LeetCode 739) using the Monotonic Stack technique, one of the most important patterns for coding interviews and competitive programming. The challenge is to determine how many days you have to wait until a warmer temperature occurs. Instead of checking every future day with a brute force approach, we use a decreasing monotonic stack to efficiently track unresolved temperatures. Whenever we encounter a warmer day, we resolve all previous temperatures that are waiting for a higher value. Throughout the video, we focus on understanding the intuition behind the Monotonic Stack before writing any code. You'll learn why this pattern works, how elements are pushed and popped, and how it helps achieve an optimal solution. A detailed dry run is included so you can confidently solve similar interview questions on your own. This pattern is widely used in many important interview problems such as Next Greater Element, Stock Span, Largest Rectangle in Histogram, Trapping Rain Water, Online Stock Span, and more. Mastering this technique will make several stack-based problems much easier. Time Complexity: O(n) Space Complexity: O(n) If you're preparing for coding interviews, placements, FAANG companies, or improving your Data Structures & Algorithms skills, this problem is a must-learn.
