Golang --对切片进行元素唯一化处理

package Tools

import "sort"

//对[]string 类型的切片进行元素唯一化处理，返回来的元素已经排好序
func SetString(arr []string) []string {
    newArr := make([]string, 0)

    for i := 0; i < len(arr); i++ {
        repeat := false
        for j := i + 1; j < len(arr); j++ {
            if arr[i] == arr[j] {
                repeat = true
            }

        }
        if !repeat {
            newArr = append(newArr, arr[i])
        }
    }
    sort.Strings(newArr)
    return (newArr)
}

//对[]int 类型的切片进行元素唯一化处理，返回来的元素已经排好序
func SetInt(arr []int) []int {
    newArr := make([]int, 0)

    for i := 0; i < len(arr); i++ {
        repeat := false
        for j := i + 1; j < len(arr); j++ {
            if arr[i] == arr[j] {
                repeat = true
            }

        }
        if !repeat {
            newArr = append(newArr, arr[i])
        }
    }
    sort.Ints(newArr)
    return (newArr)
}
//c := []interface{}{1,2,3,3,4,4}
//  d := Tools.Set(c)   //[1 2 3 4]
//注意场景切片时的语法 c := interface{}{1,1,2,2,3,3,4,5}

func Set(arr []interface{}) []interface{} {
    newArr := make([]interface{}, 0)

    for i := 0; i < len(arr); i++ {
        repeat := false
        for j := i + 1; j < len(arr); j++ {
            if arr[i] == arr[j] {
                repeat = true
            }

        }
        if !repeat {
            newArr = append(newArr, arr[i])
        }
    }

    return (newArr)
}

SetString( []string ) []string 针对 []string,
SetInt( []int ) 针对 []int ，
Set([]interface{}) []interface{} 针对 []interface{}

func main() {
    a := []string{"a","b","a","c","a","b"}
    b := Tools.SetString(a)
    fmt.Println(b)

    c := []interface{}{1,2,3,3,4,4}
    d := Tools.Set(c)   //[1 2 3 4]
    fmt.Println(d)

输出结果为

[a b c]
[1 2 3 4]
