Problem Name: 30 days of code - Day 5: Loops

Problem Link: https://www.hackerrank.com/challenges/30-loops/problem?isFullScreen=true

In this HackerRank in 30 Days of Code - Day 5: Loops problem solution,

Objective
In this challenge, we will use loops to do some math. Check out the Tutorial tab to learn more.

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.

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 * i 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
