Solution: Triangle

Understand how to use dynamic programming to find the minimum path sum in a triangular array by moving from the bottom row upward. Learn to optimize computations with a one-dimensional array and grasp the approach's time and space efficiency.

We'll cover the following...

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 ...
