### Python and C++ program to implement multiplication of 2d array (Matrix multiplication)

Here, in this program we are going to implement matrix multiplication , suppose matrix 1 has dimensions:m*n and matrix 2 has dimensions :p*q for these two matrix to be multiplied we need to have the number of columns in matrix 1(n) equal to the number of rows in matrix 2(p), if the condition is satisfied then the result of multiplication will be a matrix of order m*q in multiplication the elements of the resultant matrix will be the sum of product of corresponding elements of row(of M1) and column(of M2) //first element in 1st row in given example: res[0][0]+=mat1[0][i] * mat2[i][0] where 0<i<n or p //second element in 1st row: res[0][1]+=mat1[0][i] * mat2[i][1] where 0<i<n or p and so on………… Example : Input : 1 2 3 1 4 5 6 2 7 8 9 3 Output : 14 32 50 Input : 4 3 4 2 4 1 1 1 Output : multiplication not possible n!=p Here goes the main execution part where the calculation is been done: for ( int i = 0 ; i < r1 ; i ++) for ( int
