A typical application example is when we have a number of available intervals and another set of query intervals, for which we want to verify the overlap with the given intervals. I’m making it available if you are interested, because it’s really a waste of time to hand-code a well-known data structure. Note that the implementation doesn’t create a single sorted list of all events, rather it individually sorts arr[] and dep[] arrays, and then uses merge process of merge sort to process them together as a single sorted array.
