WebMar 26, 2015 · You would use a min-max-median heap to find the min, max and median in constant time (and take linear time to build the heap). You can use order-statistics trees to find the kth smallest/largest value. Both of these data structures are described in this paper on min-max heaps [PDF]. A radix heap is a data structure for realizing the operations of a monotone priority queue. A set of elements to which a key is assigned can then be managed. The run time of the operations depends on the difference between the largest and smallest key or constant. The data structure consists mainly of a series of buckets, the size of which increases exponentially. dr ruthnam coffs harbour

Implementation notes - Stanford University

WebWe implement a two level radix heap. Let k=sizeof (KeyType)*8 be the number of bits in a key. In contrast to an ordinary radix heap which contains k buckets, we maintain ceil (k/log2 (Radix)) rows each containing Radix-many buckets. This reduces the number of move operations when reorganizing the data structure.
