30 Days of Code - Day 5: Loops

Coding challenges are a great resource for learning coding techniques and improve analytical thinking, this is a collection of challenges from different platforms.

Objective

In this challenge, we’re going to use loops to help us do some simple 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.

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

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

Solution

package main

import "fmt"

func main() {
  var n int
  fmt.Scan(&n)

  for i := 1; i <= 10; i++ {
    fmt.Printf("%v x %v = %v\n", n, i, n*i)
  }
}
