Get an element of a sparse range array.

Parameters:

array - collection of elements applying for the ranges

offsets - starting offsets of the ranges

numberOfElements - the size of the original array

index - a position to retrieve

Throws:

IndexOutOfBoundsException - if the requested index is out of bounds
