LeetCode - Single Element in a Sorted Array

Question Definition

Given a sorted array consisting of only integers where every element appears twice except for one element which appears once. Find this single element that appears only once. Example 1:

Input: [1,1,2,3,3,4,4,8,8]
Output: 2

Example 2:

Input: [3,3,7,7,10,11,11]
Output: 10

Note: Your solution should run in O(log n) time and O(1) space.

Java Solution

public int singleNonDuplicate(int[] nums) {
    int result = nums[0];
    for(int i = 1; i < nums.length; i++)
        result = result ^ nums[i];
    return result;
}
