p01940 Unique Subsequence_35417
C: Only one subsequence --Unique Subsequence- problem One day Ebi-chan noticed that a text string T of length n and a pattern string P (m \ leq n) of length m were placed on the desk. Ebi-chan loves the "only one subsequence" that appears in strings, so she immediately began investigating whether P was the only subse...
