Basic Operation Implementation in a Binary Search Tree A sort of data structure used for data searching and organization is the binary search tree. It consists of nodes with left and right child nodes as well as key value nodes. A binary search tree's fundamental functions include finding a node with a particular key, adding new nodes, and removing existing nodes. The implementation of the search operation in a binary search tree will be the main topic of this essay. The Searching Process The key operation in a binary search tree is the search operation, sometimes referred to as the Find function. Its objective is to locate the node in a subtree that has a particular key value. The key value of the root node and the key value of the node being searched for are compared during the search process in a binary search tree. The search is finished and the root node is returned if the key value of the root node matches the key value being sought after. The search proceeds in the left subtree if the root node's key value is higher than the key value being sought after. The search moves on to the appropriate subtree if the root node's key value is smaller than the key value being sought after. Putting the Find Function in Place Recursive implementation of the Find function is possible. The root node is returned if the key value of the root node matches the key value being sought after. The Find function is called recursively on the left child of the root node if the key value of the root node is higher than the key value being sought after. The Find function is called recursively on the right child of the root node if the root node's key value is smaller than the key value being sought after. Handling Null Pointers The search function will reach a null pointer if the node with the specific key value cannot be found in the binary search tree. In this situation, changing the Find function to return the node where the key value would fit in the tree would be helpful. In a binary search tree, the implementation of the search operation entails a recursive process that compares the key value of the root node to the key value being sought for and then continues the search in the left or right subtree as appropriate. The Find function can deliver helpful information even if the node with the particular key value is not discovered in the binary search tree by being modified to support null pointers.
