Given a sorted array A[] of N positive integers having all the numbers occurring exactly twice, except for one number which will occur only once. Find the number occurring only once.
Example 1:
Input:
N = 5
A = {1, 1, 2, 5, 5}
Output: 2
Explanation:
Since 2 occurs once, while
other numbers occur twice,
2 is the answer.
Example 2:
Input:
N = 7
A = {2, 2, 5, 5, 20, 30, 30}
Output: 20
Explanation:
Since 20 occurs once, while
other numbers occur twice,
20 is the answer.
Your Task:
You don't need to read input or print anything. Your task is to complete the function search() which takes two arguments(array A and integer N) and returns the number occurring only once.
Expected Time Complexity: O(Log(N)). Expected Auxiliary Space: O(1).
