### Instructions
|
||
|
|
|
||
|
|
Write a program that prints in ascending order 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.
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is an **incomplete** output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/piscine-go/printcombprog$ go build
|
||
|
|
student@ubuntu:~/piscine-go/printcombprog$ ./printcombprog | cat -e
|
||
|
|
012, 013, 014, 015, 016, 017, 018, 019, 023, ..., 689, 789$
|
||
|
|
student@ubuntu:~/piscine-go/printcombprog$
|
||
|
|
```
|
||
|
|
|
||
|
|
`000` or `999` are not valid combinations because the digits are not different.
|
||
|
|
|
||
|
|
`987` should not be shown because the first digit is not less than the second.
