Grokking the Coding Interview Patterns in Python

Solution: Daily Temperatures

Understand how to apply a monotonic stack approach to the daily temperatures problem. This lesson guides you through using a stack to track indices of days and calculate the wait time for a warmer temperature efficiently. You will learn the algorithm's logic, time complexity of O(n), and space complexity of O(n) to confidently solve related 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 ...
