Split Array Into Chunks

Wissen Technology processes ordered event records in batches. Given an array and a positive chunk size, split the array into consecutive, non-empty chunks while preserving the original order and leaving the input array unchanged.

Formal Specification

Implement split_into_chunks(records, chunk_size).

• records is a Python list containing arbitrary values.
• chunk_size is a positive integer.
• Return a list of lists, where each inner list contains at most chunk_size consecutive elements from records.
• Every input element must appear exactly once in the output, in the same order.
• The final chunk may contain fewer than chunk_size elements.
• Return an empty list when records is empty.

Examples

Example 1

Input: records = [1, 2, 3, 4, 5, 6, 7], chunk_size = 3
Output: [[1, 2, 3], [4, 5, 6], [7]]

The first two chunks contain three elements, and the remaining element forms the final chunk.

Example 2

Input: records = ["a", "b"], chunk_size = 5
Output: [["a", "b"]]

Because the requested size exceeds the array length, the entire array becomes one chunk.

Constraints

• 0 <= len(records) <= 10^5
• 1 <= chunk_size <= 10^5
• Elements may be any Python values.
• Do not modify records.
