Understanding the Reorder Data in Log Files Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
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: Letter-logs: All words (except the identifier) consist of lowercase English letters. Digit-logs: All words (except the identifier) consist of digits. Reorder these logs so that: The letter-logs come before all digit-logs. The letter-logs are sorted lexicographically by their contents. If their contents are the same, then sort them lexicographically by their identifiers. The digit-logs maintain their relative ordering. Return the final order of the logs.

Examples
logs = ["dig1 8 1 5 1","let1 art can","dig2 3 6","let2 own kit dig","let3 art zero"]["let1 art can","let3 art zero","let2 own kit dig","dig1 8 1 5 1","dig2 3 6"]The letter-log contents are all different, so their ordering is "art can", "art zero", "own kit dig". The digit-logs have a relative order of "dig1 8 1 5 1", "dig2 3 6".
logs = ["a1 9 2 3 1","g1 act car","zo4 4 7","ab1 off key dog","a8 act zoo"]["g1 act car","a8 act zoo","ab1 off key dog","a1 9 2 3 1","zo4 4 7"]Constraints
1 <= logs.length <= 1003 <= logs[i].length <= 100All the tokens of logs[i] are separated by a single space.logs[i] is guaranteed to have an identifier and at least one word after the identifier.How Interview Coder Helps with Leetcode Problems
