Programs A$,$ B$,$ C$,$ and D have similar

structure$$each of them consists of a single loop

that contains n statements that perform some

processing on each element of a single dimensioned array Z$.$ Other features of these programs

are as follows:

Program A: n $=4$ and Z is a huge array.

Program B: n $=100$ and Z is a huge array.

Program C: n $=4$ and Z is a small array.

Program D: n $=100$ and Z is a small

array
