[Solved] Construct Product Matrix C++, Java, Python
Given a 0-indexed 2D integer matrix grid of size n * m, we define a 0-indexed 2D matrix p of size n * m as the product matrix of grid if the following condition is met: Return the product matrix of grid. Example 1:Input: grid = [[1,2],[3,4]] Output: [[24,12],[8,6]] Explanation: p[0][0] = grid[0][1] * grid[1][0] * grid[1][1]…
