Given two matrix A and B, compute the sum of all elements in matrix A*B.
We will give you 2 instance of Matrix, you should use the provided functions to complete the task.
Followng are some explanations about the functions:
int *get_row(int row): this function will return a int* pointer that points to the elements in the row-th row of the matrix.int *get_column(int col): this function will return a int* pointer that points to the elements in the col-th column of the matrix.int get_size(): this function will return a int representing the size of the matrix (the matrix is of size*size).void remove(int *array): you should call this function to free the array returned by the previous get_row() or get_column(), otherwise you won't pass the memory check. (If you can't pass our memory check, there might be some error message in the end of your output, this will cause a Wrong Answer.)Your are required to implement the int calculate(Matrix A, Matrix B). This function will return the sum of all elements in matrix A*B.
Remember to #include "function.h" in the beginning of your code!
First line of input is an integer n, indicating that both of the matrix is of size n*n.
For the next n lines, each line i will consists of n numbers, representing the elements in the i-th row of the first matrix.
For the next n lines, each line j will consists of n numbers, representing the elements in the j-th row of the second matrix.
It is guaranteed that:
If you passed our memory check, the output will contain an integer representing the sum of the elements in matrix A*B.
Otherwise, there might be some error code, which is something that you should try to get rid of.
