Solution: Triangle

Explore how to solve the minimum path sum in a triangle array by applying dynamic programming techniques. Understand the bottom-up method that efficiently calculates the optimal path from the base to the top, using space and time efficient strategies to master this classic optimization problem.

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 ...
