Split into batches
A fulfilment system processes orders in batches. Given a list of order IDs in queue order and a batch size k (k >= 1), split the queue into consecutive batches of k orders each; the final batch keeps whatever is left over, even if fewer than k. Return the batches as a list of lists. Example: [1, 2, 3, 4, 5] with k = 2 becomes [[1, 2], [3, 4], [5]].

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
