Java Loops I

HackerRanktestinganswers.com

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 * 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<=i <= 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

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

public class Solution {
    public static void main(String[] args) throws IOException {
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));

        int N = Integer.parseInt(bufferedReader.readLine().trim());
        
        for(int i=1;i<=10;i++){
            System.out.println(N+" x "+i+" = "+N*i);
        }

        bufferedReader.close();
    }
