-/**
- * 352. Data Stream as Disjoint Intervals
- *
- * Given a data stream input of non-negative integers a1, a2, ..., an, ..., summarize the numbers seen so far as a list of disjoint intervals.
-
- For example, suppose the integers from the data stream are 1, 3, 7, 2, 6, ..., then the summary will be:
-
- [1, 1]
- [1, 1], [3, 3]
- [1, 1], [3, 3], [7, 7]
- [1, 3], [7, 7]
- [1, 3], [6, 7]
-
- Follow up:
- What if there are lots of merges and the number of disjoint intervals are small compared to the data stream's size?
