Document Processing Order Solution
Problem Statement
You are given a list of document IDs representing documents waiting to be processed. Documents are processed in a First-In-First-Out (FIFO) manner. Return a list of document IDs in the order they will be processed.
Examples
Example 1:
Input:["doc1", "doc2", "doc3"]
Output:["doc1", "doc2", "doc3"]
Explanation: Documents are processed in the exact order they are received.
Example 2:
Input:["report_a", "report_b"]
Output:["report_a", "report_b"]
Explanation: Even with different names, the FIFO principle dictates the order.
Example 3:
Input:[]
Output:[]
Explanation: An empty input list results in an empty output list.
Constraints
- The input list can contain between 0 and 1000 document IDs.
- Each document ID is a non-empty string.
- Document IDs can contain alphanumeric characters and underscores.
- The total length of all document IDs will not exceed 100,000 characters.
Time: O(N) Space: O(N)
The problem statement implies a FIFO processing order. Given an input list representing arrival order, the output list will be identical to the input list. No additional data structures or complex operations are required.
