Building and Searching a Binary Search Tree in C Language Introduction A Binary Search Tree (BST) is a special type of binary tree that has the following properties: Each node has a value. For each node, all values in its left subtree are less than the value of that node. For each node, all values … Read more
Tree Structures in C: Traversing Binary Trees In computer science, a tree is an important data structure. In particular, a binary tree is a tree structure where each node has at most two child nodes. Binary trees are widely used in various algorithms and data processing tasks, such as expression parsing and search algorithms. This … Read more
Unions in C Language: Techniques for Memory Savings In the C language, a union is a special data structure that allows storing different types of data in the same memory location. Unlike structures, which allocate independent memory for each member, a union only allocates enough space for its largest member. This makes unions an effective … Read more
