Instructions

• Write a function that prints all possible combinations of n different digits in ascending order.

• n will be defined as : 0 < n < 10

below are your references for the printing format expected.

• (for n = 1) '0, 1, 2, 3, ..., 8, 9'

• (for n = 3) '012, 013, 014, 015, 016, 017, 018, 019, 023,...689, 789'

Expected function

func PrintCombN(n int) {

}

Usage

Here is a possible program to test your function :

package main

import "piscine"

func main() {
	piscine.PrintCombN(1)
	piscine.PrintCombN(3)
	piscine.PrintCombN(9)
}

And its output :

$ go run .
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
012, 013, 014, 015, 016, 017, 018, ... 679, 689, 789
012345678, 012345679, ..., 123456789
$

Be mindful of your program efficiency to avoid timeouts.
