    64 - Minimum Path Sum.

    Medium

    Given a m x n grid filled with non-negative numbers, find a path from top left to bottom right, which minimizes the sum of all numbers along its path.

    Note: You can only move either down or right at any point in time.

    Example 1:

    Input: grid = [1,3,1,1,5,1,4,2,1]

    Output: 7

    Explanation: Because the path 1 → 3 → 1 → 1 → 1 minimizes the sum.

    Example 2:

    Input: grid = [1,2,3,4,5,6]

    Output: 12

    Constraints:

    • m == grid.length

    • n == grid[i].length

    • 1 <= m, n <= 200

    • 0 <= grid[i][j] <= 100
