Split an array into typed chunks
Split values into consecutive chunks of positive size (1 to 10000). Only the final chunk may be shorter; use a generic chunk helper. Inputs are valid JSON and must not be modified unless the algorithm uses a local copy. This exercise probes typed data modeling, boundary handling, and algorithm selection.
Input
One JSON value: { values: (string | number)[]; size: number }. See the sample for its exact shape.
Output
One compact JSON value of type (string | number)[][]. Strings include JSON quotes; arrays preserve the specified order.
Constraints
Array/string lengths are 0 to 10000 unless stated otherwise. Numbers are integers in [-1000000,1000000]; all computed results fit the safe integer range.
Example
Input
{"values":[1,2,3,4,5],"size":2}Output
[[1,2],[3,4],[5]]
Example 2 input
{"values":[1,2,3],"size":10}Output
[[1,2,3]]
Checks a boundary or contrasting case beyond the public examples.
Public test cases (2)
Input
{"values":[1,2,3,4,5],"size":2}Expected output
[[1,2],[3,4],[5]]
Input
{"values":[],"size":1}Expected output
[]
Hints (2)
- Start with the required output order and the empty-input behavior.
- Slice the array at increments of the requested size
