Webb20 mars 2024 · An RB tree is a binary search tree that contains, in addition to the key and pointers of a standard binary tree, also a binary field called color, which can be RED or BLACK. Through precise rules for coloring the nodes on any path, we obtain that no path in an RB tree is more than double than any other, resulting in an approximately balanced tree.

WebbBy property 2, any node with height h has black-height at least h/2. (At most half the nodes on a path to a leaf are red, and so at least half are black.) We can also show that the subtree rooted at any node x contains at least 2 bh(x) − 1 internal nodes. The proof is by induction on the height of x.The basis is when h(x) = 0, which means that x is a leaf, and … five ways an object\u0027s motion can change https://mkbrehm.com
