### Usage
|
||
|
|
|
||
|
|
Here is a possible program to test your function :
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
|
||
|
|
arr := [][]string{
|
||
|
|
{"foo", "boo"},
|
||
|
|
{"abc", "def"},
|
||
|
|
{"hello", "yoall"},
|
||
|
|
{"everyone", ""},
|
||
|
|
{"hello world", "fam"},
|
||
|
|
}
|
||
|
|
|
||
|
|
for
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ go run .
