It looks like code coverage decreased. Can we make sure all code paths are executed in your tests? Additionally, it would be nice if we could get a high level description of the algorithm in the comments for readability purposes.

And can we also confirm that these tests still pass before this change and after the change?

[bhautikpip]

Tests have passed in both the version before this change and after this change. Moreover, I have added description of the algorithm. Initially code coverage was decreased because in the older version we are using simple_wildcard_change which we do not require in this version so I have removed that function.

Everything looks fine. Good job!
