## removeduplicate

### Instructions

Write a function that takes a slice of integers as an argument and returns the slice where all duplicate integers have been removed.

- If the slice is empty, return the slice itself.

### Expected function

```go
func RemoveDuplicate(slice []int) []int {

}
```

### Usage

Here is a possible program to test your function:

```go
package main

import (
	"fmt"
)

func main() {
	fmt.Println(RemoveDuplicate([]int{1, 2, 3, 3, 4, 5, 6, 7, 8, 9, 10}))
	fmt.Println(RemoveDuplicate([]int{1, 1, 2, 2, 3}))
	fmt.Println(RemoveDuplicate([]int{}))
}

```

And its output:

```console
$ go run .
[1 2 3 4 5 6 7 8 9 10]
[1 2 3]
[]
```
