Tree

Binary Tree A binary tree is a tree data structure in which each node has at most two children, referred to as the left child and the right child. B-Tree A B-tree is a self-balancing tree data structure that maintains sorted data and allows searches, sequential access, insertions, and deletions in logarithmic time. It is optimized for systems that read and write large blocks of data. B+ Tree A B+ tree is an extension of a B-tree, optimized for systems that read and write large blocks of data. [Read More]

Data Structure Interview

What is the difference between an array and a linked list? Array: Fixed size (in most languages) Contiguous memory allocation Fast random access Insertion/deletion is expensive (except at the end) Linked List: Dynamic size Non-contiguous memory allocation Slow random access Fast insertion/deletion Explain the difference between a stack and a queue. Stack: Last-In-First-Out (LIFO) structure Push (insert) and pop (remove) operations occur at the same end Used for function calls, undo mechanisms, expression evaluation Queue: [Read More]
