Webnaments, and we obtain two new variants of binomial queues, a one-tree version and a one-pass version. We extend the one-pass version to support key decrease operations, obtaining the rank-pairing heap, or rp-heap. Rank-pairing heaps combine the performance guarantees of Fibonacci heaps with simplicity approaching that of pairing heaps. Web– make-heap: return a new, empty heap. – insert(x;H): insert item x, with predeﬁned key and currently in no heap, into heap H. – find-min(H): return the item in heap Hof minimum key. – delete-min(h): if heap His not empty, delete from Hthe item of minimum key. – meld(H 1;H 2): return a heap containing all the items in disjoint heaps ... cine theatre martin
