HackerRank Java Loops I - Problem Statement

Objective

In this challenge, we're going to use loops to help us do some simple math.

Task

Given an integer, N, print its first 10 multiples. Each multiple N x i (where 1<= i <= 10) should be printed on a new line in the form: N x i = result.

Input Format

A single integer, N.

Constraints

2 <= N <= 20

Output Format

Print 10 lines of output; each line i (where 1<= i <= 10) contains the result of N * i in the form:

N x i = result.

Sample Input:

3 (code-box)

Sample Output:

2 x 1 = 2 2 x 2 = 4 2 x 3 = 6 2 x 4 = 8 2 x 5 = 10 2 x 6 = 12 2 x 7 = 14 2 x 8 = 16 2 x 9 = 18 2 x 10 = 20 (code-box)

Java Loops I – Hacker Rank Solution

Approach I:

import java.io.*;
import java.math.*;
import java.security.*;
import java.text.*;
import java.util.*;
import java.util.concurrent.*;
import java.util.regex.*;

public class Solution {



    private static final Scanner scanner = new Scanner(System.in);

    public static void main(String[] args) {
        int N = scanner.nextInt();
        scanner.skip("(\r\n|[\n\r\u2028\u2029\u0085])?");
        int i;
        for(i=1;i<=10;i++)
        {
            System.out.println(+N +" x "+i+" = "+N*i);
        }
        scanner.close();
    }
}

Approach II:

import java.io.*;
import java.util.*;

public class Solution {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int N = in.nextInt();
        
        for( int i = 1; i <= 10; i++ ) {
            System.out.println( N + " x " + i + " = " + N*i);
        }
    }
}

Approach III:

import java.io.*;
import java.util.*;

public class Solution {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int N = scanner.nextInt();
        
        for (int i = 1; i <= 10; ++i) {
            System.out.printf("%d x %d = %d\n", N, i, N * i);
        }
    }
}

Approach IV:

import java.io.*;
import java.util.*;

public class Solution {

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        for(int i = 1; i<=10; i++)
            {
            int result=n*i;
            System.out.println(n+" x "+i+" = "+result);
        }
    }
}
