%N Number of winning length n strings with a 10-symbol alphabet in "same game".
%C Strings that can be reduced to null string by repeatedly removing an entire run of two or more consecutive symbols.
%C For binary strings, the formula for the number of winning strings of length n has been conjectured by Ralf Stephan and proved by Burns and Purcell (2005, 2007). For b-ary strings with b >= 3, the same problem seems to be unsolved. - _Petros Hadjicostas_, Aug 31 2019
