trySplit()
If this spliterator can be partitioned, returns a Spliterator
covering elements, that will, upon return from this method, not
be covered by this Spliterator.

Spliterator.OfDouble trySplit()
Spliterator
If this Spliterator is Spliterator.ORDERED
, the returned Spliterator
must cover a strict prefix of the elements.
Unless this Spliterator covers an infinite number of elements,
repeated calls to trySplit()
must eventually return null
.
Upon non-null return:
estimateSize()
before splitting,
if not already zero or Long.MAX_VALUE
, must, after splitting, be
greater than estimateSize()
for this and the returned
Spliterator; andSUBSIZED
, then estimateSize()
for this spliterator before splitting must be equal to the sum of
estimateSize()
for this and the returned Spliterator after
splitting.This method may return null
for any reason,
including emptiness, inability to split after traversal has
commenced, data structure constraints, and efficiency
considerations.
