b. Rewrite the following function to use pointer arithmetic instead of array subscripting. (In other words, eliminate the variables i and j and all of the [] operator.) Use a single loop instead of nested loops. Note: al0 is of type int [LEN] and therefore a[0 is an int constant pointer pointing to the first int of the LEN ints, i.e. a[0 or *a is an int pointer pointing to a[0][0] int sum_two_dimensional_array(const int al [LEN], int n) int i, j, sum = 0; for ( i = 0; i
