Employee ID Registry

You are given a list of employee IDs. Each ID consists of letters followed by digits (like 'abc123', 'xyz456'). Your task is to sort these IDs first by the numeric part in ascending order and then by the alphabetical part. Input will be multiple lines, each containing one employee ID. Output the sorted list of IDs, one per line. Example: Input: xyz456 abc123 abc789 xyz123 Output: abc123 xyz123 xyz456 abc789
