I would be grateful, if anyone could

  • point out why the below solution TLEd?

  • give hints to improve the code running time?

Logic explanation in plain english:

  • Create a dictionary of string, int.

  • the key stores the patterns of len 19 for each number w.r.t to parity of each digit e.g ( 00000000101010111011 )

  • the count of pattern is incremented, decremented accordingly.

  • Ans is just a dictionary lookup for given pattern
