WebDec 7, 2024 · Because the heap is initially empty, you can't have more deletes than inserts. An amortized cost of O (1) per deletion and O (log N) per insertion is exactly the same as an amortized cost of O (log N) for both inserts and deletes, because you can just count the deletion cost when you do the corresponding insert.
