반응형

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
