NettetIn computer science, a leftist tree or leftist heap is a priority queue implemented with a variant of a binary heap.Every node x has an s-value which is the distance to the nearest leaf in subtree rooted at x. In contrast to a binary heap, a leftist tree attempts to be very unbalanced.In addition to the heap property, leftist trees are maintained so the right … In computer science, a leftist tree or leftist heap is a priority queue implemented with a variant of a binary heap. Every node x has an s-value which is the distance to the nearest leaf in subtree rooted at x. In contrast to a binary heap, a leftist tree attempts to be very unbalanced. In addition to the heap property, … Se mer The usual leftist tree is a height-biased leftist tree. However, other biases can exist, such as in the weight-biased leftist tree. Se mer Most operations on a Height Biased Leftist Tree are done using the merge operation. Merging two Min HBLTs The merge operation … Se mer Several variations on the basic leftist tree exist, which make only minor changes to the basic algorithm: • The choice of the left child as the taller one is arbitrary; a … Se mer • Leftist Trees, Sartaj Sahni Se mer The s-value (or rank) of a node is the distance from that node to the nearest empty position in the subtree rooted at that node. Put another way, the s-value of a null child is implicitly zero. Other nodes have an s-value equal to one more the minimum of their … Se mer Leftist trees can also be weight biased. In this case, instead of storing s-values in node x, we store an attribute w(x) denoting the number of nodes in the subtree rooted at x: Se mer • Robert E. Tarjan (1983).
