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.

\n\n

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

\n\n

Example 1:

\n\"\"\n
\nInput: grid = [[1,3,1],[1,5,1],[4,2,1]]\nOutput: 7\nExplanation: Because the path 1 → 3 → 1 → 1 → 1 minimizes the sum.\n
\n\n

Example 2:

\n\n
\nInput: grid = [[1,2,3],[4,5,6]]\nOutput: 12\n
