Burst Balloons
Detailed guide and Python implementation for the 'Burst Balloons' problem.
Problem Statement
You are given n balloons, indexed from 0 to n - 1. Each balloon is painted with a number on it represented by an array nums. You are asked to burst all the balloons.
If you burst the ith balloon, you will get nums[i - 1] * nums[i] * nums[i + 1] coins. If i - 1 or i + 1 goes out of bounds of the array, then treat it as if there is a balloon with a 1 painted on it.
Return the maximum coins you can collect by bursting the balloons wisely.
Write a function maxCoins(nums: List[int]) -> int.
- •n == len(nums)
- •1 <= n <= 300
- •0 <= nums[i] <= 100
Examples
nums = [3,1,5,8]
167
burst 1 -> burst 5 -> burst 3 -> burst 8. Coins: 3*1*5 + 3*5*8 + 1*3*8 + 1*8*1 = 167.
nums = [1,5]
10
burst 1 first: 1*5*1 = 5, then burst 5: 1*5*1 = 5. Total = 10.
