Day 5: Loops | 30 Days Of Code | HackerRank Solution

Hello coders, today we are going to solve Day 5: Loops HackerRank Solution in C++, Java and Python.

Day 5: Loops

Contents

Objective

In this challenge, we will use loops to do some 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.

Example

n = 3

The printout should look like this:

3 x 1 = 3
3 x 2 = 6
3 x 3 = 9
3 x 4 = 12
3 x 5 = 15
3 x 6 = 18
3 x 7 = 21
3 x 8 = 24
3 x 9 = 27
3 x 10 = 30

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 x 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

Solution – Day 5: Loops

C++

#include <bits/stdc++.h>

using namespace std;

int main()
{
    int n;
    cin >> n;
    cin.ignore(numeric_limits<streamsize>::max(), '\n');
    
    if(2<=n<=20)
    {
        for (int i = 1; i <= 10; i++) 
        {
            cout <<n<<" "<<"x"<<" "<<i<<" "<<"="<<" "<<(n*i)<< endl;
        }
    }
    return 0;
}

Java

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])?");

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

Python

#!/bin/python3

import math
import os
import random
import re
import sys



if __name__ == '__main__':
    n = int(input())
    for i in range ( 1, 11 ):
        print ( n, "x", i, "=", n*i)
