 * 1) There can be 90 numbers to write.


 * 1) 0 Planck times. Proof:


 * 1) Assuming blank paper: 0 Planck times: since there're 0 numbers (essentially same as blank input), all numbers are even, and all numbers are odd.


 * 1) Assuming 1 number as input: 0, since 1 number is either even or odd, it's impossible to have neither.
