(c) Consider the following two C functions sum2Darray1 and sum2Darray2. Both of them compute the sum of all the elements of an input 2-dimensional matrix. Which one of them will be able to exploit memory hierarchy and thus achieve faster com- putation time? Explain your answer. 1 int sum2Darray1 (int a [N] [M]) 2 { 3 4 5 6 780 8} int i, j, sum=0; for(i=0; i
