[Solved] 3ple Newton’s Triwizard Contest with Java

You are given a positive integer N. Print “Yes” if N is a multiple of 3, otherwise print “No”.

Input

The input consists of a single integer N.

Constraints:
1 ≤ N ≤ 1000

Output

If N is a multiple of 3, print “Yes”. Otherwise, print “No” (without the quotation marks). Note that the output is case-sensitive.

Example

Sample Input 1:
6

Sample Output 1:
Yes

Sample Input 2:
10

Sample Output 2:
No

Solution

Approach: The problem is simple. If the number is divisible by 3, then it is a multiple of 3. Otherwise, it is not a multiple of 3.

import java.io.*; // for handling input/output
import java.util.*; // contains Collections framework

// don't change the name of this class
// you can add inner classes if needed
class Main {
    public static void main (String[] args) {
        // Your code here
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        if (n % 3 == 0) {
            System.out.println("Yes");
        } else {
            System.out.println("No");
        }
    }
}
