Given a list of integers, made up of (hopefully) a small number of long runs
|
of consecutive integers, compute a representation of the form
|
((start1, end1), (start2, end2) ...). Then answer the question "was x present
|
in the original list?" in time O(log(# runs)).

|
((start_0, end_0), (start_1, end_1), ...), such that the original
|
integers are exactly those x such that start_i <= x < end_i for some i.
|
|
Ranges are encoded as single integers (start << 32 | end), not as tuples.
