Given an array of numbers nums, in which exactly two elements appear only once and all the other elements appear exactly twice. Find the two elements that appear only once.For example:Given nums = [1, 2, 1, 3, 2, 5], return [3, 5].Note:1.The order of

给定一个整数数组,除了某个元素外其余元素均出现两次.请找出这个只出现一次的元素.备注:你的算法应该是一个线性时间复杂度. 你可以不用额外空间来实现它吗? 详见:https://leetcode.com/problems/single-number/description/ Java实现: class Solution { public int singleNumber(int[] nums) { int n=nums.length; if(n==0||nums==null){ return In
