Question :
A Meera number is a number such that the number of nontrivial factors is a factor of the number. For example, 6 is a Meera 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 Meera number. Another Meera number is 30 because 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 Meera Number. However 21 is not a Meera 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 Meera number.
Write a function named isMeera that returns 1 if its integer argument is a Meera number, otherwise it returns 0.
The signature of the function is
int isMeera(int n)
Solution :

Solution :
public static int
isMeeraNumber(int n)
{
int count = 0,rtnVal=0;
for(int i=2;i<n;i++)
{
if(n%i==0)
{
count++;
}
}
for (int i = 2; i < n; i++)
{
if (n % i
== 0)
{
if(count==i)
{
rtnVal = 1;
break;
}
}
}
return rtnVal;
}
the last for is not necessary
