longer explained here.Iv. addition of red and black treesThe red and black tree itself is a binary search tree, meaning that the value of a node must not be less than the value of its left child, and not greater than the value of its right child. When a node is added, traversing from the root, it will be possible to f

Red-black Trees?Red-black trees is one of the many search-tree schemes that is "balanced" in order to guarantee that basic Dynamic-set opera tions take O (LGN) time in the worst case.Red-black trees? is one of many search tree frameworks. These trees take the self-balance in

image. You can swap the Left and Right of case 3. 5. If the parent node of the node to be inserted is red and the uncle node is red, as follows: At this time, you only need to black out the Father's Day node and Uncle node, and red the grandfather node. The above is the

the root node splitting This insertion is equivalent to inserting elements into this can cause the height of the tree to change the disadvantage of storing in 3 nodes, with the insertion of 3 nodes to the root node, and then through the root of the division of the entire tree is increased by 1, it can be seen that 3 nodes and the associated insertion method is to ensure the balance of the key, It can also be seen that the growth of 2-3 trees grows from the bottom up through the root node. 2-3 t

Introduction The red/black tree is a self-balancing Binary Search Tree. Its statistical performance is better than that

Before we learned the binary search tree, we found that in some cases its height is not very uniform, and sometimes degenerate into a long chain, so we refer to some "balanced" two-fork search tree. The red and black tree is a "balanced" two-fork search tree, which ensures that in the worst case, the time complexity of the basic dynamic set operation is O (NLGN)

The two-fork search tree is described earlier, and he has no problem with the efficiency of finding and inserting in most cases, but he is less efficient in the worst case. The data structure of the balanced lookup tree introduced in this article and later in this article ensures that the LGN efficiency can be achieved in the worst case, and we need to make sure that the tree remains in equilibrium after th

In practice, we do not directly use the Binary Search Tree, because the performance of the Binary Search Tree is heavily dependent on the insertion sequence of elements, especially when an element is inserted in an ascending manner, in this case, the binary search tree will become a linked list. In practical applications, we use the "balanced" binary search tree, including the AVL, red,

. Therefore, we can find a way to restore the black height of the original path containing y nodes. The practice is:Unconditionally push the black color of the Y node to its sub-node X.. (X may be a nil node ). In this way,X may have both black and red colors., That is, 1st items are damaged.However, the 1st items are
