数组中只出现一次的数字

package main

import "fmt"

func main() {
	/*
		示例 1：
		输入：nums = [4,1,4,6]
		输出：[1,6] 或 [6,1]
	*/

	var nums = []int{4, 1, 4, 6, 9, 3}
	res := singleNumbers(nums)
	fmt.Println(res) // [1 6 9 3]

}

func singleNumbers(nums []int) []int {
	var s []int
	for i := 0; i < len(nums); i++ {
		var count int
		for j := 0; j < len(nums); j++ {
			if nums[i] != nums[j] {
				count++
			}
		}
		if count == len(nums)-1 {
			s = append(s, nums[i])
		}
	}
	return s
