|
|
|
|
```go
|
|
|
|
|
package main
|
|
|
|
|
|
|
|
|
|
import (
|
|
|
|
|
"fmt"
|
|
|
|
|
"piscine"
|
|
|
|
|
)
|
|
|
|
|
|
|
|
|
|
func main() {
|
|
|
|
|
|
|
|
|
|
result := []string{"a", "A", "1", "b", "B", "2", "c", "C", "3"}
|
|
|
|
|
piscine.AdvancedSortWordArr(result, piscine.Compare)
|
|
|
|
|
|
|
|
|
|
fmt.Println(result)
|
|
|
|
|
}
