Summary

Given an array of arrays, this method generates a series of new arrays where the first contains all first elements, the second all second elements, and so on, effectively extracting specific rows from the nested structure.

When applied to a large array where it is known to be already sorted, a user can pass the `isSorted` parameter to trigger a binary search for faster efficiency. Alternatively, by passing a specific number as the third argument, the function searches for the first matching value in the array that follows the specified index.

This approach allows for an $O(n)$ solution by utilizing binary search to locate the correct row or value within the sorted dataset.
