A red-black tree is a BST with two node types, namely red and black, and supporting operations that ensure the tree is balanced when a node is inserted or removed. Rules:Every node is colored either red or black.The root node is black.A red node's children cannot be red. A null child is considered to be a black leaf node.All paths from a node to any null leaf descendant node must have the same n..

AVL InsertionsInserting an item into an AVL tree may cause the tree to become temporarily unbalanced. A rotation can rebalance the tree.If you have read the pseudocode of rotation carefully, you would've noticed that there is a case labeled as Double Rotation case, where we need to apply two rotations for rebalancing. In the following case, we apply double right rotation at C to rebalance the AV..

Tree Rotation For Balancing Inserting an item into an AVL tree may require rearranging the tree to maintain height balance. A rotation is a local rearrangement of a BST that maintains the BST ordering property while rebalancing the tree. *Rotation is said to be done at a node. Ex. Above, the right rotation is done at node 86.In the example above, if the node 75 had a right child, then the right..
