Perfect number
Perfect number is sum of the Divisors equal to the given number.
Example-1:
Input : n = 6 Output : Perfect number Explain : Divisors of 6 is (1,2,3) and sum all the values 1+2+3=6.
Example-2:
Input : n = 8 Output : Not a Perfect number Explain : Divisors of 8 is (1,2,4) and sum all the values 1+2+4=7.
Solution
public class Main
{
public static void main(String [] args)
{
int n = 6,sum = 0;
for(int i=1;i<n;i++)
{
if(n%i==0)
{
sum = sum + i;
}
}
if(sum==n)
{
System.out.print("Perfect number");
}
else
{
System.out.print("Not a Perfect number");
}
}
}
n = 6
k = 0
for i in range(1,n):
if(n % i == 0):
k += i
if(n==k):
print("Perfect number")
else:
print("Not a Perfect number")
Output
Perfect number
