In the worst case, we may need to go from the root node to the deepest leaf node, which is the entire height of the treeh. If the tree is unbalanced, i.e. it is skewed, the height of the tree may becomen, so the worst case time complexity of insertion and search operations isO...

Two binary search trees can store the same values in different ways: Some trees (like AVL trees or Red-Black trees) rearrange nodes as they're inserted to ensure the tree is always balanced. With these, the worst case complexity for searching, inserting, or deleting isalwaysO(lg(n))O(lg...

However, we aim to control the shape of the tree in order to ensure a logarithmic complexity. Many approaches have been proposed in the literature in order to achieve efficient maintenance for the tree, mainly if they are binary, with the aim of finding a balance criteria that ensures a ...
are fairly simple to implement. The main challenge comes with the threading or rethreading of the neighbor links with insertions or deletions, but the complexity of adding or removing an element from a linked list pales in comparison to the complexity of balancing an AVL or red-black tree. ...
