Solution: Triangle

Understand how to apply dynamic programming to find the minimum path sum in a triangle array by iteratively calculating optimal subproblems from the bottom up. This lesson helps you develop an efficient solution that minimizes time and space complexity, preparing you to handle similar optimization problems.

Statement

Given an array, triangle, return the minimum path sum from top to bottom.

You may move to an adjacent number in the row below at each step. More formally, if you are at index ii in the current row, you may move to either index ii ...
