Which one of the following statements about the function Process Array is CORRECT?
Consider the C function given below. Assume the array listA contains (n>0) elements, sorted in ascending order.

int Process array (int * list A, int x, int n)
{
int i, j, k;
i =0;j=n-1;
do {
k = (i+j)/2;
if (x<=list A[k])
j=k-1;
if (list A[k] <=x)
i =k+1;
} while (i <=j);
if (list A[k] == x)
return (k);
else
return -1;
}

AIt will run into an infinite loop when x is not in listA

BIt is an implementation of binary search.

CIt will always find the maximum element in listA.

DIt will return -1 even when x is present in listA.

Choose the correct option.

Select the code snippet which returns the top of the stack.

I. public int top()
{
if(q1.size()>0)
{
return q1.poll();
}
else if(q2.size()>0)
{
return q2.poll();
}
return 0;
}

II. public int top()
{
if(q1.size()==0)
{
return q1.peek();
}
else if(q2.size()==0)
{
return q2.peek();
}
return 0;
}

III. public int top()
{
if(q1.size()>0)
{
return q1.peek();
}
else if(q2.size()>0)
{
return q2.peek();
}
return 0;
}

IV. public int top()
{
if(q1.size()>0)
{
return q2.peek();
}
else if(q2.size()>0)
{
return q1.peek();
}
return 0;
}


AI

BII

CIII

DIV

Answer: Option C

Explanation:

Assuming its a push costly implementation, the top of the stack will be in the front end of the queue, note that peek() just returns the front element, while poll() removes the front element from the queue.
