 #include<stdio.h>

int main(){
   int number,i,result=0;//declare variables and initialize result to 0
   printf("enter the number:");
   scanf("%d",&number);
   for(i=1;i<=number;i++){
      if(number%i==0)
         result=result+i;
   }
   if(result==2*number) //checking the sum of factors==2*number
      printf("perfect number");
   else
      printf("not perfect number");
}
