Solution: Minimum Path Sum

Explore how to determine the minimum path sum from the top-left to the bottom-right of a grid using dynamic programming. Understand the in-place update of the grid to compute minimal path costs efficiently, and develop skills to implement this solution in C++ with optimized time and space complexity.

Statement

You are given an m × n grid containing non-negative integers. Your task is to find a path from the top-left cell to the bottom-right cell that minimizes the sum of the values along the path. At each step, you may move only right or down.

Constraints:

  • m == grid.length

  • n == grid[i].length ...
