LeetCode #739 — Daily Temperatures. Solve on LeetCode, then implement here if you want it in your drill queue.

https://leetcode.com/problems/daily-temperatures/

## The mechanism

A stack is last-in-first-out: the last thing you pushed is the first thing you pop. Reach for one when the natural question is "what was the most recent unfinished thing?" — parsing, recursion, undo, matching brackets.

## Expected evidence

Pass all LeetCode test cases for this problem.

## Hints

- Pattern hint: stack.
- Start with brute force, then optimize time/space.
- Write down invariants before coding.
