중복 항목을 만들지 않고 Go에서 슬라이스 항목을 어떻게 이동합니까?

<code class="go">slice := []int{0,1,2,3,4,5,6,7,8,9}

indexToRemove := 1
indexWhereToInsert := 4

slice = append(slice[:indexToRemove], slice[indexToRemove+1:]...)
newSlice := append(slice[:indexWhereToInsert], 1)
slice = append(newSlice, slice[indexWhereToInsert:]...)</code>

<code class="go">func insertInt(array []int, value int, index int) []int {
    return append(array[:index], append([]int{value}, array[index:]...)...)
}

func removeInt(array []int, index int) []int {
    return append(array[:index], array[index+1:]...)
}</code>

<code class="go">func moveInt(array []int, srcIndex int, dstIndex int) []int {
    value := array[srcIndex]
    return insertInt(removeInt(array, srcIndex), value, dstIndex)
}</code>

<code class="go">func main() {
    slice := []int{0,1,2,3,4,5,6,7,8,9}

    fmt.Println("Original slice:", slice)

    slice = insertInt(slice, 2, 5)
    fmt.Println("After insertion:", slice)

    slice = removeInt(slice, 5)
    fmt.Println("After removal:", slice)

    slice = moveInt(slice, 1, 4)
    fmt.Println("After moving:", slice)
}</code>

Original slice: [0 1 2 3 4 5 6 7 8 9]
After insertion: [0 1 2 3 4 2 5 6 7 8 9]
After removal: [0 1 2 3 4 5 6 7 8 9]
After moving: [0 2 1 3 4 5 6 7 8 9]
