Consider the function in C code :

Cal(a, b)

{

    if (b != 1)

    {

        if (a != 1)

        {

            printf("*");

            Cal(a/2, b);

        }

    }

    else

    {

        b = b - 1;

        Cal(10, b);

    }

}

How many times * is going to be printed, if the function is called with


Cal(10, 10) ?

Solution

Observe recursion:

Each call prints * while dividing a by 2.

Sequence:

10 → 5 → 2 → 1

For each b value, stars printed = 3.

b decreases from 10 to 1.

Thus:

$9 \times 3 = 27$

Total stars printed = 27.
