## sum |
||||
|
||||
### Instructions |
||||
|
||||
Write a function that takes two single digit numbers as a string and returns the sum as an int. If one of the arguments is not a single digit number, return 0; |
||||
|
||||
### Expected function |
||||
|
||||
```go |
||||
func Sum(a,b string) int { |
||||
|
||||
} |
||||
``` |
||||
|
||||
### Usage |
||||
|
||||
Here is a possible program to test your function : |
||||
|
||||
```go |
||||
package main |
||||
|
||||
import ( |
||||
"piscine" |
||||
"fmt" |
||||
) |
||||
|
||||
func main() { |
||||
fmt.Println(piscine.Sum("1", "2")) |
||||
fmt.Println(piscine.Sum("-4", "0")) |
||||
fmt.Println(piscine.Sum("7", "-3")) |
||||
} |
||||
``` |
||||
|
||||
And its output : |
||||
|
||||
```console |
||||
$ go run . | cat -e |
||||
3$ |
||||
-4$ |
||||
4$ |
||||
$ |
||||
``` |
