A representation of binary tree is shown:Binary Tree: Common TerminologiesRoot: Topmost node in a tree. Parent: Every node (excluding a root) in a tree is connected by a directed edge from exactly one other node. This node is called a parent. Child: A node directly connected to another ...

A binary heap is a tree created using a binary tree. It can be seen as a binary tree with two additional constraints: Shape property: A binary heap is a complete binary tree; that is, all levels of the tree, except possibly the last one (deepest) are fully filled, and, if the last...

The below diagram shows a BST Representation: Above shown is a sample BST. We see that 20 is the root node of this tree. The left subtree has all the node values that are less than 20. The right subtree has all the nodes that are greater than 20. We can say that the above tree ...
The encoding is based in the representation of both a vertex spanning tree of the graph and the complementary spanning tree of the dual of the graph. Additionally, Ferres et al. proposed a PRAM EREW algorithm to construct their encoding in \(O(\lg ^2m\lg ^*m)\) time using O(m) ...
A Balanced Binary Tree is a type of binary search tree where the height of the tree is proportional to log base 2 of the number of elements it contains. This balanced structure ensures efficient searching, with elements being found by inspecting at most a few nodes. ...

Using Binary Indexed Tree, we can do both tasks inO(Logn) time.The advantages of Binary Indexed Tree over Segment are, requires less space and very easy to implement.. Representation Binary Indexed Tree is represented as an array. Let the array be BITree[]. Each node of Binary Indexed Tre...
