"Web28 nov. 2012 · 2 Answers. A min-heap typically only supports a delete-min operation, not an arbitrary delete (x) operation. I would implement delete (x) as a composition of decrease-key (x, − ∞ ), and delete-min. Recall, that to implement decrease-key, you would bubble up the element to maintain the heap property (in this case all the way to the root). " - Max heap deletion algorithm
