About the pattern
The merge intervals pattern is all about working with time ranges that might overlap. Each time range, or interval, is defined by a start and an end point—for example, [10, 20] means the range starts at 10 and ends at 20. The pattern works by identifying overlapping intervals and merging them into one. If there is no overlap, the interval is kept as it is. Let’s take a look at the illustration to help visualize this.
