-/**
- * 57. Insert Interval
- *
- * Given a set of non-overlapping intervals, insert a new interval into the intervals (merge if necessary).
-
- You may assume that the intervals were initially sorted according to their start times.
-
- Example 1:
- Given intervals [1,3],[6,9], insert and merge [2,5] in as [1,5],[6,9].
-
- Example 2:
- Given [1,2],[3,5],[6,7],[8,10],[12,16], insert and merge [4,9] in as [1,2],[3,10],[12,16].
-
- This is because the new interval [4,9] overlaps with [3,5],[6,7],[8,10].
