2123132133 has the property that no subsequence of length 3 is the same as any other subsequence of length 3.
Your task is to build a program that will output as long of a string as possible that satisfies this property for sequences of length 9 with the characters from
The source code of your program may not be longer than 16 kilobytes (16,384 bytes). The program that wins is the one that outputs the longest sequence of digits from
9 such that no subsequence of 9 digits is the same.
