may be broken during the insertion process, so we need to make a simple correction to the tree, namely the rotation of the AVL tree.Setting a node loses its balance after inserting the next node, which can occur in four situations:1. Insert the left sub-tree of A's left son. (left-left)2. Insert the right sub-tree of the left son of a. (left-right)3. Insert the

In discrete mathematics, no-root tree refers to non-ring connected undirected graphs.A tree without root is a two-tuple (v,e), of which: 1. V is a non-empty set, called a vertex set. 2.E is a set of unordered two-tuple groups of elements in V, called Edge sets.Intuitively, if each edge of a graph is a direction-free, i

Topic Description: In a tree full of two. The sort tree depth is k, the node number is 2^k-1, the node value is 1 to (2^k-1), the value of K and any three nodes is given, and the root node of the most young tree containing the three nodes is output. Sample input: 4 10 15 13 Sample output: 12 First, let's take a look at

04-Tree 5 Root of AVL Tree (25 min) An AVL tree is a self-balancing binary search tree. In a AVL tree, the heights of the subtrees of any node differ by at the most one; If at any time they differ by more than one, the rebalancing

An example of hash's application in the competition of Informatics "It is easy to think of an algorithm that uses two strings to represent two shards, But what should we do if we use hash?You can use a tree-like Recursive Method to Calculate the hash value: For a node v, first obtain the hash values of all its son nodes and sort them in ascending order as H1, H2, „, HD. Then the hash value of V can be calculated: (A * P) ^ H1 mod q) * P ^ H2 mod q )..

For example: the input depth is 4, the three subnodes are 10,13,15, and the minimum subtree is 12. We can infer that this is a median traversal value from 1 to 2^k-1 according to the tree traversal method. We can use the binary search technology to find the root node of the oldest tree.
