WebJan 18, 2007 · To quote Linux Weekly News: There are a number of red-black trees in use in the kernel. The deadline and CFQ I/O schedulers employ rbtrees to track requests; the packet CD/DVD driver does the same. The high-resolution timer code uses an rbtree to organize outstanding timer requests. The ext3 filesystem tracks directory entries in a red-black tree. WebA radix tree is a tree where a node can have any number of children. Each edge leading from a node to a child has a label (usually a string). A radix tree is often used to store strings or IP addresses. By traversing from the root to any leaf in the tree, concatenating all the labels of edges along the way, you can find any string. onshape ifc

A radix tree, also known as compressed trie or compressed prefix tree, is a tree-like data structure for storing a set of strings. The edges of the tree are labeled by nonempty strings, and each node is either terminal or nonterminal. The strings that the tree contains are exactly the labels of all paths from the root to a ...
