How do you chunk an array?

4. Split the other part into two using split2 .

What is array chunking?

How do you split an array into two subarrays?

Given an array of integers greater than zero, find if it is possible to split it in two subarrays (without reordering the elements), such that the sum of the two subarrays is the same. Print the two subarrays.
