Largest rectangle in histogram

CodingAlgorithms & data structuresSenior–Staff~30 min

Given an array heights representing the heights of adjacent bars in a histogram where each bar has width 1, return the area of the largest rectangle that fits entirely within the histogram. Heights are non-negative integers, and 1 <= len(heights) <= 10^5.

Implement
largest_rectangle_area(heights: list[int]) → int

What a strong answer looks like

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
