方法一:

//这种发放适用于string,int,float等切片,会对切片中的元素进行排序

package test

import (
	"sort"
)

func SliceRemoveDuplicates(slice []string) []string {
	sort.Strings(slice)
	i := 0
	var j int
	for {
		if i >= len(slice)-1 {
			break
		}

		for j = i + 1; j < len(slice) && slice[i] == slice[j]; j++ {
		}

		slice = append(slice[:i+1], slice[j:]...)
		i++
	}

	return slice
}

 

 

方法二:

package test

func RemoveDuplicate(list *[]int) []int {
	var x []int
	for _, i := range *list {
		if len(x) == 0 {
			x = append(x, i)
		} else {
			for k, v := range x {
				if i == v {
					break
				}

				if k == len(x)-1 {
					x = append(x, i)
				}
			}
		}
	}
	return x
}
