1 Consider the following array int a 1 2 3 4 5 4 3 2 1 0

1.   Consider the following array:

int[] a = { 1, 2, 3, 4, 5, 4, 3, 2, 1, 0 };


What are the contents of the array a after each of the following loops complete?

a.   for (int i = 1; i < 10; i++) { a[i] = a[i - 1]; }

b.   for (int i = 9; i > 0; i--) { a[i] = a[i - 1]; }

c.    for (int i = 0; i < 9; i++) { a[i] = a[i + 1]; }

d.   for (int i = 8; i >= 0; i--) { a[i] = a[i + 1]; }

e.   for (int i = 1; i < 10; i++) { a[i] = a[i] + a[i - 1]; }

f.     for (int i = 1; i < 10; i = i + 2) { a[i] = 0; }

g.   for (int i = 0; i < 5; i++) { a[i + 5] = a[i]; }

for (int i = 1; i < 5; i++) { a[i] = a[9 - i]; }

Solution


Given:
  
   int[] a = { 1, 2, 3, 4, 5, 4, 3, 2, 1, 0 };

   size = 10


a)
   for (int i = 1; i < 10; i++) {
       a[i] = a[i - 1];
   }

   a = [ 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 ]

b)
   for (int i = 9; i > 0; i--) { a[i] = a[i - 1]; }

   a = [ 1, 1, 2, 3, 4, 5, 4, 3, 2, 1 ]

c)
   for (int i = 0; i < 9; i++) { a[i] = a[i + 1]; }
  
   a = [ 2, 3, 4, 5, 4, 3, 2, 1, 0, 0 ]

d. for (int i = 8; i >= 0; i--) { a[i] = a[i + 1]; }
  
       a = [ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]


e. for (int i = 1; i < 10; i++) { a[i] = a[i] + a[i - 1]; }

   a = [ 1, 3, 6, 10, 15, 19, 22, 24, 25, 25 ]


f. for (int i = 1; i < 10; i = i + 2) { a[i] = 0; }

       a = [ 1, 0, 3, 0, 5, 0, 3, 0, 1, 0 ]


g. for (int i = 0; i < 5; i++) { a[i + 5] = a[i]; }

       a = [ 1, 2, 3, 4, 5, 1, 2, 3, 4, 5 ]

h. for (int i = 1; i < 5; i++) { a[i] = a[9 - i]; }

       a = [ 1, 1, 2, 3, 4, 4, 3, 2, 1, 0 ]
