Question
You start at the top-left cell of a grid of heights and want to reach the bottom-right. You may move up, down, left, or right. A route's 'effort' is the maximum absolute height difference between two consecutive cells along the route. Return the minimum effort required to travel from top-left to bottom-right. Grid dimensions are at least 1x1; a 1x1 grid needs effort 0.
minimum_effort_path(heights: list[list[int]]) → int[[[1,2,2],[3,8,2],[5,3,5]]]out2State 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.
Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.
