     Example:
-
     f(0) = 0 -- smallest non-negative
-
     f(1) = 1 -- smallest non-negative, which is not yet in the sequence
-
     f(2) = 3 -- since 0, 1, 2 form an arithmetic progression
-
     f(3) = 4 -- neither of 0, 1, 4, 0, 3, 4, 1, 3, 4 form an arithmetic
     progression, so we can take smallest non-negative, which is larger than 3
-
     f(4) = 9 -- 5, 6, 7, 8 are not good, since 1, 3, 5, 0, 3, 6, 1, 4, 7, 0, 4, 8
