A binary search tree (BST) is a binary tree in which each node has at most two children, and it facilitates fast search, insertion, and deletion operations. The time complexity of each operation is O(log n), which is considerably faster than linear search. The two main characteristics of...
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 log...

Structures in an efficient way in Java with references to time and space complexity. These Pre-cooked and well-tested codes help to implement larger hackathon problems in lesser time. DFS, BFS, LCA, LCS, Segment Tree, Sparce Table, All Pair Shortest Path, Binary Search, Matching and many ...
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. ...
