Grokking the Coding Interview Patterns in C++

Solution: Daily Temperatures

Explore how to solve the Daily Temperatures problem using a monotonic stack. This lesson teaches you to track indices and compare temperatures efficiently to determine wait times for warmer days. You will understand the algorithm's linear time complexity and space usage, helping you implement stack-based solutions in C++ for similar coding interview questions.

We'll cover the following...

Statement

Given an array of integers, temperatures, that represents daily temperatures, return an array, output, where each element, output[i], indicates the number of days you need to wait after the ithi^{th} day to experience a warmer temperature if there is no future day with a higher temperature, set output[i] to 0.

Constraints:

  • 1≤1 \leq temperatures.length ≤103 \leq 10^3 ...
