Largest histogram rectangle

CodingAlgorithms & data structuresMid–Senior~30 min

Given the heights of bars in a histogram (each bar has width 1), find the area of the largest axis-aligned rectangle that fits entirely within the histogram. Return that maximum area. Constraints: 0 <= n <= 10^5, 0 <= height[i] <= 10^4.

Implement
largest_rectangle(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.
