[2018.12.16] Loops

Problem

Objective 
In this challenge, we're going to use loops to help us do some simple math. Check out the Tutorial tab to learn more.

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

Input Format

A single integer, .

Constraints

Output Format

Print  lines of output; each line  (where ) contains the  of  in the form: 
n x i = result.

Sample Input

2

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

How I solved the problem

# 단순 반복문 문제. output처럼 나오도록 println에서 맞춰주는것도 중요!

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 loop = 10;
        
        for (int i = 0; i < loop; i++) {
            int multiple = i + 1;
 
            System.out.println(n + " x " + multiple + " = " + (n * multiple));
        }
        scanner.close();
    }
}
