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]…

Chef is given two binary strings A and B, each having length N. Chef wants to find the number of binary strings �C, of length �N, such that �(�,�)=�(�,�)H(A,C)=H(B,C), where �(�,�)H(X,Y) denotes the hamming distance between the strings �X and �Y. Since the answer can be large, output it modulo 109+7109+7. Note: Hamming distance between two strings…
