You are given an array of logs
. Each log is a space-delimited string of words, where the first word is the identifier.
There are two types of logs:
\n\nReorder these logs so that:
\n\nReturn 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\n1 <= logs.length <= 100
3 <= logs[i].length <= 100
logs[i]
are separated by a single space.logs[i]
is guaranteed to have an identifier and at least one word after the identifier.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 。
有两种不同类型的日志:
\n\n请按下述规则将日志重新排序:
\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
\n\n
提示:
\n\n1 <= logs.length <= 100
3 <= logs[i].length <= 100
logs[i]
中,字与字之间都用 单个 空格分隔logs[i]
