You are given an array of logs. Each log is a space-delimited string of words, where the first word is the identifier.

\n\n

There are two types of logs:

\n\n\n\n

Reorder these logs so that:

\n\n
    \n\t
  1. The letter-logs come before all digit-logs.
  2. \n\t
  3. The letter-logs are sorted lexicographically by their contents. If their contents are the same, then sort them lexicographically by their identifiers.
  4. \n\t
  5. The digit-logs maintain their relative ordering.
  6. \n
\n\n

Return the final order of the logs.

\n\n

 

\n

Example 1:

\n\n
\nInput: logs = ["dig1 8 1 5 1","let1 art can","dig2 3 6","let2 own kit dig","let3 art zero"]\nOutput: ["let1 art can","let3 art zero","let2 own kit dig","dig1 8 1 5 1","dig2 3 6"]\nExplanation:\nThe letter-log contents are all different, so their ordering is "art can", "art zero", "own kit dig".\nThe digit-logs have a relative order of "dig1 8 1 5 1", "dig2 3 6".\n
\n\n

Example 2:

\n\n
\nInput: logs = ["a1 9 2 3 1","g1 act car","zo4 4 7","ab1 off key dog","a8 act zoo"]\nOutput: ["g1 act car","a8 act zoo","ab1 off key dog","a1 9 2 3 1","zo4 4 7"]\n
