Single element in a sorted array | Leetcode
This video explains a very important programming interview question which is to find the unique element in a sorted array in just O(logN) time and O(1) extra space. This problem would have been extremely easy to solve provided we were allowed O(N) time. This can be solved by simple linear search or XOR operation. In order to take benefit of sorted array property, we can use binary search algorithm with some observations to find the unique element in just O(logN). I have shown 4 observations and used them to solve the problem in O(logN) time using binary search algorithm.At the end of the video, i have explained the CODE. CODE LINK is present below as usual.
