Solution

a) As there are four iterations in L1 label , hence DMEM is called 4 times.

b) Data after each iteration is:

1st iteration:

$3 = 4

$4= 5

$20 = 4

$21 = 5

$22 = 1

$23 = 50

2nd iteration:

$3 = 8

$4= 15

$20 = 4

$21 = 10

$22 = 1

  $23 = 50

3rd iteration:

$3 = 12

$4= 30

$20 = 4

$21 = 15

$22 = 1

$23 = 50

4th and final iteration:

$3 = 16

$4= 50

$20 = 4

$21 = 20

$22 = 0

$23 = 50
