- There are N pancakes with diameters 1:N.
- Spatula can be inserted anywhere in the stack and used to flip all the pancakes above.
- Sort pancakes in increasing order.
- Return a vector of places where spatula was inserted.
- Minimize number of flips, your score will depend on the number of flips in the last few tests.

William Gates and Christos Papadimitrou solved this problem, before the former left to co-found Microsoft. Very interesting problem indeed.
Is the scoring system still working?
Lincoln, I checked the reference solution and it showed that the manual scoring system no longer works.
I will see what changes I can do and notify it here.
Unfortunately, the scoring system is broken (same as in the TRON challenge by Alfonso).
No way to get the Indexing IV badge :-(
@Stefan, I have commented out the part that outdated and the test suite is working now.
I have rescored your solution, you can now (hopefully) get the Indexing IV badge!
