Daily Temperatures - LeetCode 739

🔥 LeetCode 739: Daily Temperatures - C++ Solution Explained In this video, I solve LeetCode problem #739 - Daily Temperatures using C++ with an efficient monotonic stack approach! ⏱️ Time Complexity: O(n) 💾 Space Complexity: O(n) 📌 Problem Overview: Given an array of integers temperatures representing daily temperatures, return an array answer such that answer[i] is the number of days you have to wait after the ith day to get a warmer temperature. If there is no future day for which this is possible, keep answer[i] == 0. Example: temperatures = [73,74,75,71,69,72,76,73] Output: [1,1,4,2,1,1,0,0] 💡 Solution Approach: - Use a monotonic decreasing stack to track indices - Store temperatures that haven't found their warmer day yet - When we find a warmer temperature, pop from stack and calculate the difference - Efficient one-pass solution that processes each element exactly once! - Stack ensures we always find the next warmer temperature in O(1) amortized time 🔗 LeetCode Problem Link: https://leetcode.com/problems/daily-temperatures/ 📚 Classic monotonic stack problem - essential pattern for technical interviews! ⭐ If this helped you, please like and subscribe for more coding solutions! #leetcode #cpp #dsa #coding #programming #monotonicstack #stack #arrays #interview #faang #mediumleetcode
