Program to check the given number is Perfect number or not

 Program to check the given number is Perfect number or not


I/P:

6


O/P:

Perfect


Explanation :


6 divisors are 2 , 3 ,1  its sum is equal to the given num so its a perfect num


PROGRAM:

import java.util.*;
public class perfect {

    public static void main(String[] args) {
    
        Scanner sc=new Scanner(System.in);
        int iNum=sc.nextInt();
        int sum=0;
        int a=iNum;
        for(int i=1;i<iNum;i++)
        {
            if(iNum%i==0)
            {
                sum+=i;
            }
        }
        if(sum==a)
        {
            System.out.println("Perfect");
        }
        else {
            System.out.println("Not Perfect");
        }

    }

}


// 6

//2 3 1=>2 + 3 +1=6==6
// Perfect

TELEPHONE BOOK USING HASHMAP

  Sample Input 3 sam 99912222 tom 11122222 harry 12299933 sam edward harry Sample Output sam=99912222 Not found harry=12299933 Explanation We add the following    (Key,Value)  pairs to our map so it looks like this: We then process each query and print  key=value  if the queried   is found in the map; otherwise, we print  Not found . Query 0:   sam Sam is one of the keys in our dictionary, so we print  sam=99912222 . Query 1:   edward Edward is not one of the keys in our dictionary, so we print  Not found . Query 2:   harry Harry is one of the keys in our dictionary, so we print  harry=12299933 . SOLUTION: package   H acker R ank_problems . practice_problems ; import   java . util .*; import   java . io .*; public   class   TelephoneBook {      public   static   void   main ( String  [] argh ){          Scanne...
