Interview question of the issue #329 of rendezvous with cassidoo.
There is a sorted integer array that has been rotated an unknown number of times. Given that rotated array, return how many times it has been rotated. It may contain duplicate numbers!
Example:
> rotatedNum([4, 0, 1, 2, 3])
> 1
> rotatedNum([7, 9, 20])
> 0
> rotatedNum([7, 7, 314, 1337, 7])
> 4Just pnpm i to install all dependencies and then pnpm t to run the tests!
