| 37 | /* | ||
| 38 | * This file defines five types of data structures: singly-linked lists, | ||
| 39 | * lists, simple queues, tail queues, and circular queues. | ||
| 40 | * | ||
| 41 | * A singly-linked list is headed by a single forward pointer. The | ||
| 42 | * elements are singly linked for minimum space and pointer manipulation | ||
| 43 | * overhead at the expense of O(n) removal for arbitrary elements. New | ||
| 44 | * elements can be added to the list after an existing element or at the | ||
| 45 | * head of the list. Elements being removed from the head of the list | ||
| 46 | * should use the explicit macro for this purpose for optimum | ||
| 47 | * efficiency. A singly-linked list may only be traversed in the forward | ||
| 48 | * direction. Singly-linked lists are ideal for applications with large | ||
| 49 | * datasets and few or no removals or for implementing a LIFO queue. | ||
| 50 | * | ||
| 51 | * A list is headed by a single forward pointer (or an array of forward | ||
| 52 | * pointers for a hash table header). The elements are doubly linked | ||
| 53 | * so that an arbitrary element can be removed without a need to | ||
| 54 | * traverse the list. New elements can be added to the list before | ||
| 55 | * or after an existing element or at the head of the list. A list | ||
| 56 | * may only be traversed in the forward direction. | ||
| 57 | * | ||
| 58 | * A simple queue is headed by a pair of pointers, one the head of the | ||
| 59 | * list and the other to the tail of the list. The elements are singly | ||
| 60 | * linked to save space, so elements can only be removed from the | ||
| 61 | * head of the list. New elements can be added to the list after | ||
| 62 | * an existing element, at the head of the list, or at the end of the | ||
| 63 | * list. A simple queue may only be traversed in the forward direction. | ||
| 64 | * | ||
| 65 | * A tail queue is headed by a pair of pointers, one to the head of the | ||
| 66 | * list and the other to the tail of the list. The elements are doubly | ||
| 67 | * linked so that an arbitrary element can be removed without a need to | ||
| 68 | * traverse the list. New elements can be added to the list before or | ||
| 69 | * after an existing element, at the head of the list, or at the end of | ||
| 70 | * the list. A tail queue may be traversed in either direction. | ||
| 71 | * | ||
| 72 | * A circle queue is headed by a pair of pointers, one to the head of the | ||
| 73 | * list and the other to the tail of the list. The elements are doubly | ||
| 74 | * linked so that an arbitrary element can be removed without a need to | ||
| 75 | * traverse the list. New elements can be added to the list before or after | ||
| 76 | * an existing element, at the head of the list, or at the end of the list. | ||
| 77 | * A circle queue may be traversed in either direction, but has a more | ||
| 78 | * complex end of list detection. | ||
| 79 | * | ||
| 80 | * For details on the use of these macros, see the queue(3) manual page. | ||

| 87 | * The caveat is that on other systems some other header | ||
| 88 | * must provide NULL before the macros can be used. | ||

| 32 | * This file defines data structures for different types of trees: | ||
| 33 | * splay trees and red-black trees. | ||
| 34 | * | ||
| 35 | * A splay tree is a self-organizing data structure. Every operation | ||
| 36 | * on the tree causes a splay to happen. The splay moves the requested | ||
| 37 | * node to the root of the tree and partly rebalances it. | ||
| 38 | * | ||
| 39 | * This has the benefit that request locality causes faster lookups as | ||
| 40 | * the requested nodes move to the top of the tree. On the other hand, | ||
| 41 | * every lookup causes memory writes. | ||
| 42 | * | ||
| 43 | * The Balance Theorem bounds the total access time for m operations | ||
| 44 | * and n inserts on an initially empty tree as O((m + n)lg n). The | ||
| 45 | * amortized cost for a sequence of m accesses to a splay tree is O(lg n); | ||
| 46 | * | ||
| 47 | * A red-black tree is a binary search tree with the node color as an | ||
| 48 | * extra attribute. It fulfills a set of conditions: | ||
| 49 | * - every search path from the root to a leaf consists of the | ||
| 50 | * same number of black nodes, | ||
| 51 | * - each red node (except for the root) has a black parent, | ||
| 52 | * - each leaf node is black. | ||
| 53 | * | ||
| 54 | * Every operation on a red-black tree is bounded as O(lg n). | ||
| 55 | * The maximum height of a red-black tree is 2lg (n+1). | ||
