It says this problem is a follow up for Search in Rotated Sorted Array.

Search in Rotated Sorted Array is a hard level question.

It is kinda un-intuitive for a medium level question to be a follow up for a hard question since I am doing all medium level questions first before I do hard level questions.

If this problem is easier than Search in Rotated Sorted Array, then I think Search in Rotated Sorted Array should be the follow up problem for this, not the other way around.
