DIY: Minimum Path Sum

Understand how to find the minimum path sum in a 2D grid by moving right or down. Learn to implement an efficient algorithm in Rust that optimizes route selection, preparing you for coding interviews involving matrix-based pathfinding problems.

Problem statement

For this problem, you are given a 2D matrix of size m x n. The matrix is filled with positive integers, which represent the cost of going from one cell in the matrix to the next. You can ...
