{ "data": { "question": { "questionId": "974", "questionFrontendId": "937", "categoryTitle": "Algorithms", "boundTopicId": 2292, "title": "Reorder Data in Log Files", "titleSlug": "reorder-data-in-log-files", "content": "

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

 

\n

Constraints:

\n\n\n", "translatedTitle": "重新排列日志文件", "translatedContent": "

给你一个日志数组 logs。每条日志都是以空格分隔的字串，其第一个字为字母与数字混合的 标识符 。

\n\n

有两种不同类型的日志：

\n\n\n\n

请按下述规则将日志重新排序：

\n\n\n\n

返回日志的最终顺序。

\n\n

 

\n\n

示例 1：

\n\n
\n输入：logs = [\"dig1 8 1 5 1\",\"let1 art can\",\"dig2 3 6\",\"let2 own kit dig\",\"let3 art zero\"]\n输出：[\"let1 art can\",\"let3 art zero\",\"let2 own kit dig\",\"dig1 8 1 5 1\",\"dig2 3 6\"]\n解释：\n字母日志的内容都不同，所以顺序为 \"art can\", \"art zero\", \"own kit dig\" 。\n数字日志保留原来的相对顺序 \"dig1 8 1 5 1\", \"dig2 3 6\" 。\n
\n\n

示例 2：

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