|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
- Write a function that takes a slice in parameter and swaps the two first element then return the new value
|
||
|
|
- If the slice contains less than two elements return the same slice.
|
||
|
|
|
||
|
|
### Expected function
|
||
|
|
|
||
|
|
```go
|
||
|
|
func SwapFirst(slice []int) []int {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a possible program to test your function :
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
fmt.Println(SwapFirst([]int{1,2,3,4}))
|
||
|
|
fmt.Println(SwapFirst([]int{3,4}))
|
||
|
|
fmt.Println(SwapFirst([]int{1}))
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ go run .
|
||
|
|
[2,1,3,4]
|
||
|
|
[4,3]
|
||
|
|
[1]
|
||
|
|
```
