Question

^_^ can u help me for this one?

Answer 1

I used brute force method. Perhaps there is more elegant way to do this...... maybe not.
public class Perfect{
public static void main (String[]args){
for(int i=1; i<=500;i++){
int r=0;
for(int c=i/2;c>=1;c--){
if(i%c==0){
r+=c;
if(r==i&& c==1){
System.out.println(i+" is a perfect number");
}
}
}
}
}
}

Answer 2

currently there are only 44 perfect numbers known , just program them hardcoded into an array. and look them up.
