printcomb
Instructions
Write a function that prints, in ascending order and on a single line: all unique combinations of three different digits so that, the first digit is lower than the second, and the second is lower than the third.
These combinations are separated by a comma and a space.
Expected function
func PrintComb() {
}
Usage
Here is a possible program to test your function :
package main
func main() {
PrintComb()
}
This is the incomplete output :
$ go run . | cat -e
012, 013, 014, 015, 016, 017, 018, 019, 023, ..., 689, 789$
$
-
000or999are not valid combinations because the digits are not different. -
987should not be shown because the first digit is not less than the second.
