Step-by-step output of numbers with a one-second pause

Create a program that outputs the next number from 1 to 10 every second.

package main

import (
    "fmt"
    "time"
)

func main() {
    for i := 1; i <= 10; i++ {
        printNumber(i)
    }
}

func printNumber(num int) {
    time.Sleep(time.Second)
    fmt.Println(num)
}
