I need to count the total number of nodes in binary tree. The problem now arise when I execute this code, it's giving garbage value for total number of nodes. The output of my program is like You declare c but not initialize nowhere and also not used in anywhere.
Binary Search Tree(BST)
Inserting nodes in a binary search tree (C) - Stack Overflow
Binary tree is one of the data structures that are efficient in insertion and searching operations. Binary tree is basically tree in which each node can have two child nodes and each child node can itself be a small binary tree. To understand it, below is the example figure of binary tree. Binary tree works on the rule that child nodes which are lesser than root node keep on the left side and child nodes which are greater than root node keep on the right side. Same rule is followed in child nodes as well that are itself sub-trees. Like in above figure, nodes 2, 4, 6 are on left side of root node 9 and nodes 12, 15, 17 are on right side of root node 9. Binary tree is created by inserting root node and its child nodes.
C++ Programming Code Examples
We have discussed BST search and insert operations. In this post, the delete operation is discussed. When we delete a node, three possibilities arise. Copy contents of the inorder successor to the node and delete the inorder successor. Note that inorder predecessor can also be used.
The left and right subtree each must also be a binary search tree. There must be no duplicate nodes. The above properties of Binary Search Tree provides an ordering among keys so that the operations like search, minimum and maximum can be done fast. If there is no ordering, then we may have to compare every key to search for a given key. Searching a key For searching a value, if we had a sorted array we could have performed a binary search.
