Java Loops I
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 <= 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
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
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
Sample Output
2 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
Java-Source Code
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 i, N = scanner.nextInt(); scanner.skip("(\r\n|[\n\r\u2028\u2029\u0085])?"); for(i = 1; i <= 10; i++){ //System.out.printf("%d x %d = %d\n", N, i, N*i); System.out.println(+N+" x "+i+" = "+N*i); } scanner.close(); } }
Sample Output
2 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
