void fun(int a, int b, int c)
{
              a= b == c;
              printf(“%d”,a);
}

Question 5

Initially a priority queue had 5 elements and it is being implemented as Max-Heap. Let’s say the level order traversal of the heap is: 30, 18, 17, 12, 11. Now two more elements are inserted into the heap i.e. 10 and 19 in the same order. The level order traversal of the heap after the insertion is:

• A30, 18, 19, 12, 11, 10, 17
• B30, 19, 18, 12, 11, 17, 10
• C30, 18, 17, 12, 11, 10, 19
• D30, 18, 19, 12, 11, 17, 10

Question 6

Consider a program which stores the frequency of marks of student in a particular subject say Mathematics. The marks is in the range [0...100] and there are around 500 students. But there is one condition we only want to record frequency if the student has passed in the exam, the passing marks being 40. What is the best way to store the frequency of marks above 40?

• AAn array of 500 numbers
• BAn array of 101 numbers
• CAn array of 39 numbers
• DAn array of 61 numbers
