|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Write a function that takes as an argument a slice of integers and return another slice of integers with the last two elements swapped.
|
||
|
|
|
||
|
|
> If the slice contains less than two elements return the same slice.
|
||
|
|
|
||
|
|
### Expected function
|
||
|
|
|
||
|
|
```go
|
||
|
|
func SwapLast(slice []int) []int {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a possible program to test your function:
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
"piscine"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
fmt.Println(piscine.SwapLast([]int{1, 2, 3, 4}))
|
||
|
|
fmt.Println(piscine.SwapLast([]int{3, 4, 5}))
|
||
|
|
fmt.Println(piscine.SwapLast([]int{1}))
|
||
|
|
}
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output:
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ go run .
|
||
|
|
[1 2 4 3]
|
||
|
|
[3 5 4]
|
||
|
|
[1]
|
||
|
|
```
