Question

You have balloons in a row; nums[i] holds a coin value. Bursting balloon i earns nums[left]*nums[i]*nums[right] coins where left and right are the adjacent still-unburst balloons (treat out-of-range as 1). Burst all balloons to maximize total coins. Return the maximum. 1 <= len(nums) <= 300, 0 <= nums[i] <= 100.

Implement

max_burst_coins(nums: list[int]) → int

Examples

in[[3,1,5,8]]out167

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.

Learn the concepts

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.

Run or narrate your approach, then ask the coach.
