A linked list is a non-contiguous storage structure where logical ordering is maintained through node references. It belongs to the linear data structure category. Data Field: Contains element values Pointer Field: Stores references to adjacent nodes Classification Criteria Linked lists are categori...
The foundation of efficient search operations relies on the divide-and-conquer principle applied to monotonic or structured datasets. The standard implementation maintains two pointers, typically left and right, converging toward a target state. To prevant infinite loops and ansure precise boundary...
Core Bucket Architecture Hash tables relying on chaining require a lightweight link node structure. Each node stores the payload and a pointer to the subsequent element within the same collision bucket. template <typename Payload> struct ChainLink { Payload data; ChainLink* next_node; ChainLin...
A doubly circular linked list is a sophisticated data structure that enhances the basic linked list concept. Unlike singly linked lists, each node in this structure contains pointers to both its successor and predecessor nodes. The "circular" aspect means the last node points back to the f...
Linear structures consist of a finite sequence of elements with identical properties. Common linear data structures include arrays, linked lists, stacks, queues, and strings. While linear structures follow a continuous logical arrangement, their physical storage may be either contiguous or non-conti...
Array-Based Linear List Manipulations The following implementation uses a fixed-size array to simulate a dynamic linear list. All mutations reflect directly on a global counter size. Core Operation Implementations #include <iostream> const int CAPACITY = 10000; int buffer[CAPACITY]; int size =...
Working with singly linked lists requires a firm grasp of pointer manipulation and edge-case handling. The following sections break down three classic problems: removing nodes by value, building a custom linked list with index-based operations, and reversing a list in-place. Eliminating Nodes with a...
Understanding Union-Find Union-Find is a data structure designed to manage relationships between sets, enabling operasions like determining set membership and merging distinct sets. Consider a practical scenario: Initially, Xiao Ming belongs to one family set and Xiao Hong to another. When they marr...
A heap is a complete binary tree structure typically implemented using a dynamic array. This implementation focuses on a min-heap, where the root node holds the smallest value and each parent node is less than or equal to its children. Data Structure and Function Prototypes #ifndef HEAP_H #define HE...
Problem Overview Consider an n×m grid where each cell contains its position number: the cell at row i, column j holds value (i-1)×m + j. We process q queries, each specifying a position (x, y). The queried element is removed and appended to the end of its row, while the element displaced from the ro...
