Regan Barron · Answer 1

(d) 6

Explanation:

When we call factorial (3) first it will check if it greater than 1 since it is greater then return 3*factorial (2) will be called on factorial (2) it will again check that 2>1 since it is greater then return 2*factorial (1) will be called. In factorial (1) we have is not greater than 1 so it will return 1. return 2*factorial (1) will return 2 and 2 that is returned by factorial (2) will be multiplied with 3. So it will return 6.
