A Bishal number is a number such that the number of nontrivial factors is a factor of the number. For example, 6 is a Bishal number because 6 has two nontrivial factors : 2 and 3. (A nontrivial factor is a factor other than 1 and the number). Thus 6 has two nontrivial factors. Now, 2 is a factor of 6. Thus the number of nontrivial factors is a factor of 6. Hence 6 is a Bishal number. Another Bishal number is 30because 30 has 2, 3, 5, 6, 10, 15 as nontrivial factors. Thus 30 has 6 nontrivial factors. Note that 6 is a factor of 30. So 30 is a Bishal Number. However 21 is not a Bishal number. The nontrivial factors of 21 are 3 and 7. Thus the number of nontrivial factors is 2. Note that 2 is not a factor of 21. Therefore, 21 is not a Bishal number. Write a function named isBishal that returns 1 if its integer argument is a Bishal number, otherwise it returns 0.
The signature of the function is int isBishal(int n)
