Delete Overlapping Intervals

You are given a two-dimensional array intervals, as an argument. Each element of intervals represent an arbitrary interval, such as [start, end]. There are overlapping intervals in intervals and you need to combine the intervals so that they do not overlap.

More specifically, the overlapping intervals are like below:

intervals = [
  [1, 3],
  [2, 4],
  [5, 7],
];

In this example, [1, 3] which is intervals[0] and [2, 4] which is intervals[1] are overlapping intervals. By combining intervals[0] and intervals[1], you can get [1, 4].

So output will be like below:

[ [1, 4], [5, 7] ]
