Question

The following code segment is a count-controlled loop going from 1 through 5. At each iteration, the loop counter is either printed or put on a queue depending on the boolean result returned by the method random. (Assume that random randomly returns either true or false.) At the end of the loop, the elements in the queue are removed and printed. Because of the logical properties of a queue, this code segment cannot print certain sequences of the values of the loop counter. You are given an output and asked to determine whether the code segment could generate the output.

for (count =1; count <= 5; count++)

{

   if (random())

   System.out.println(count);

   else

   queue.enqueue(count);

   }

   while (!queue.isEmpty())

   {

   number = queue.dequeue();

   System.out.println(number);

}

The following output is possible: 1 2 3 4 5

   i. True       ii. False   iii. Not enough info.

b. The following output is possible: 1 3 5 4 2

   i. True       ii. False   iii. Not enough info.

c. b. The following output is possible: 1 3 5 2 4

   i. True       ii. False   iii. Not enough info.
