937. Reorder Data in Log Files Medium

1/**
2 * [937] Reorder Data in Log Files
3 *
4 * You are given an array of logs. Each log is a space-delimited string of words, where the first word is the identifier.
5 * There are two types of logs:
6 * 
7 * 	Letter-logs: All words (except the identifier) consist of lowercase English letters.
8 * 	Digit-logs: All words (except the identifier) consist of digits.
9 * 
10 * Reorder these logs so that:
11 * <ol>
12 * 	The letter-logs come before all digit-logs.
13 * 	The letter-logs are sorted lexicographically by their contents. If their contents are the same, then sort them lexicographically by their identifiers.
14 * 	The digit-logs maintain their relative ordering.
15 * </ol>
16 * Return the final order of the logs.
17 *  
18 * Example 1:
19 * 
20 * Input: logs = ["dig1 8 1 5 1","let1 art can","dig2 3 6","let2 own kit dig","let3 art zero"]
21 * Output: ["let1 art can","let3 art zero","let2 own kit dig","dig1 8 1 5 1","dig2 3 6"]
22 * Explanation:
23 * The letter-log contents are all different, so their ordering is "art can", "art zero", "own kit dig".
24 * The digit-logs have a relative order of "dig1 8 1 5 1", "dig2 3 6".
25 * 
26 * Example 2:
27 * 
28 * Input: logs = ["a1 9 2 3 1","g1 act car","zo4 4 7","ab1 off key dog","a8 act zoo"]
29 * Output: ["g1 act car","a8 act zoo","ab1 off key dog","a1 9 2 3 1","zo4 4 7"]
30 * 
31 *  
32 * Constraints:
33 * 
34 * 	1 <= logs.length <= 100
35 * 	3 <= logs[i].length <= 100
36 * 	All the tokens of logs[i] are separated by a single space.
37 * 	logs[i] is guaranteed to have an identifier and at least one word after the identifier.
