This is based on Ch12, exercise 17. Recall how 2D arrays are represented in memory. You are provided a C file called sum-2d-array.c that contains the function sum_two_dimensional_array shown below. You are also provided a Makefile that compiles the program. Rewrite the given function to use pointer arithmetic instead of array subscripting. In other words, eliminate the variables i and j and all uses of the [ operator. Use a single loop instead of nested loops and do not change the function signature. int sum_ two_dimensional_array(int al l[LEN], int n)t int i, j, sum0; for (i -0; i
