Can you solve this real interview question? Single Element in a Sorted Array - You are given a sorted array consisting of only integers where every element appears exactly twice, except for one element which appears exactly once. Return the single eleme
因为既要比较前面的数,又要比较后面的数,数组的第一和最后一个数就要单独判断。所以我的第一个算法是这样的: publicintsingleNonDuplicate(int[] nums) {intn =nums.length;if(nums.length <= 2)returnnums[0];if(nums[0] != nums[1])returnnums[0];if(nums[n - 1] != nums[n - 2])returnnums...
540. Single Element in a Sorted Array 题目大意: 给你一个由小到大排好序的数组,里面只有一个数出现了一次,其他数都出现了两次,要求找出那个只出现一次的数,而且时间复杂度为O(logn) 题目思路: 说实话一开始没想到,因为几乎每个数都出现了两次那么对于一个偶数i,一定有nums[i] == nums[i+1]否则说明在...
