[Hackerrank] Loops

dhjo ㅣ 2021. 9. 29. 03:04

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

Example

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
