Please add tests showing how it works. It seems that it won't work for arrays with duplicate elements

Can you tell me where to add the tests. I added 3 testcases in the file as comments.
As for duplicate elements, I am checking the script and will update the PR

Hey @siriak , I couldn't find a solution for duplicate elements. If there are duplicate elements then maybe the complexity has to go up. Can you tell me where to add the tests(I don't know about them, can you explain)?

And, I found out, I can add the solution to another such question:
Given a rotated sorted array(rotated from its initial sorted position.), search for an element.
Input-Output:
Eg. [11,12,15,18,2,5,6,8]
Search Element: 6
Position: 6
Again, in O(log n) time.

Just mention in the description that the array cannot contain duplicates. As for tests, we don't have anything set up, so your comments will serve the purpose.

Done it. Thanks!
