解法都在代码里,不懂就留言或者私信 这个题不知道为啥会考,过于简单了,我解题+写注释用了两分钟不到,5行代码。。。 class Solution {public int singleNumber(int[] nums) {/**这个题目确实时间的题,根据位运算法则我们知道1.两个相同的数异或之后是02.任何数和0异或之后是它本身所以我们考虑拿所有的数进行异或,因为其他数都出现两次,所以其他
Given an array of integers, every element appears twice except for one. Find that single one. Note: Your algorithm should have a linear runtime complexity. Could you implement it without using extra
今天又来做题了,因为Find the Duplicate Number一直没想出来,但又不想直接上网看答案,只好做与它类似的题目。 Single Number Given an array of integers, every element appears twice except for one. Find that single one. Note: Your algorithm s
Find the kth largest element in an unsorted array. Note that it is the kth largest element in the sorted order, not the kth distinct element. For example, Given [3,2,1,5,6,4] and k = 2, return 5.
