Aamod Garg, it is not appropriate to effectively publish the solution as a comment. The instruction asks Players to "crack" the sequence. —DIV [Can some Admin possibly please delete Aamod Garg's comment?]

The Integer Sequence isn't shown for some reason.

I don't see an integer sequence here

The integer sequence is not shown (at least for me), but you can get the idea from the test cases. Here is the sequence, if you are looking for it: 1, 1, 1, 2, 5, 21, 233, 10946, 5702887...

These numbers are from the original Fibonacci sequence. To crack it, you'll need to find the relationship between these numbers and their indices.

Probably the most satisfactory problem I've encountered this far. Wonderful!

Little coding, more time spent figuring out the sequence.
