GoLang有序列表去重

package main

func arrUnique(arr []int)[]int{
    i := 0
    length := len(arr)
    for j:=1;j<length;{
        j++
        if arr[i+1] != arr[j]{
            arr[i+1] = arr[j]
            i++
        }
    }
    length +1
    return arr[:length]
}

func main(){
    arr := []int{1, 1, 1, 2, 3, 3, 4, 4, 4, 4, 4, 5, 6, 6, 6, 6, 6, 6, 6, 7, 8, 9, 10, 10, 10}
    fmt.Println(arr)
    res := arrUnique(arr)
    fmt.Println(res)
}

结果：
