Daily Temperatures
TIME: O(n)
SPACE: O(n)
Problem Statement
Given an array of integers temperatures representing the 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 instead.
Real Engineering Applications
In production systems, this concept directly maps to caching index layers, route lookups optimizations, compiler scope parsing validations, and multi-thread dependency schedulers.
