WebDeleting a Node. This process makes use of decrease-key and extract-min operations. The following steps are followed for deleting a node. Let k be the node to be deleted. Apply decrease-key operation to decrease the value of k to the lowest possible value (i.e. -∞). Apply extract-min operation to remove this node. 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.
