Daily Temperatures (LeetCode 739) | Full solution with animations and examples | Study Algorithms

A very interesting problem that involves the use of stack data structure. Using this hint, given an array of integers that represent the temperature at that day, return an array that represents the next warmer day. It also sounds like a straight forward extension of finding the Next Greater Element. Watch the video to understand how elements are added and popped from the stack, to solve this problem in the most efficient way. All of this with animations and a dry-run of code in JAVA.
