Heap Data Structure is a special case of balanced binary tree data structure where the root-node key is compared with its children and arranged accordingly. Min-Heap − Where the value of the root node is less than or equal to either of its children. Max-Heap − Where the value of the root node is greater ...
Array is defined as an ordered set of similar data items. All the data items of an array are stored in consecutive memory locations in RAM. The elements of an array are of same data type and each item can be accessed using the same name. Takeaways What is Array in Data Structure? An array is a data ...
A stack in data structure, following the Last In First Out (LIFO) principle, is a crucial linear data structure for sequential task completion. Imagine entering a crowded elevator last and exiting first; this mirrors stack behavior. Understanding this, we’ll explore the formal definition of a stack data structure in C++. Some Key Points Related to ...
Data structures and algorithms form the backbone of computer science, enabling efficient problem-solving and optimization of software applications. Data structures organize and store data, while algorithms provide step-by-step procedures for solving computational problems. Together, they empower programmers to create efficient and scalable solutions, making them fundamental concepts for anyone delving into the world of programming and ...
A tree data structure organizes data hierarchically, comprising nodes connected by edges. The root stands atop, branching out to child nodes, each potentially having its own sub-nodes, creating a recursive pattern. In contrast, linear structures like arrays, linked lists, stacks, and queues arrange elements sequentially. The choice between these structures hinges on several factors. Firstly, the nature ...
A Doubly Linked List enhances the standard Linked List by allowing bidirectional navigation. Each node points to both the next and the previous node, enabling efficient forward and backward traversal. This structure contrasts with Single Linked Lists, where movement is restricted to one direction, making it challenging to access previous elements without iterating from the start. What ...
What is Priority Queue? A priority queue serves as a specialized data structure where elements are organized based on their priority values, ensuring that higher-priority items are processed before lower-priority ones. This organization enables efficient retrieval of the most critical elements. Various implementations, such as arrays, linked lists, heaps, or binary search trees, offer different ...
The Knuth-Morris-Pratt (KMP) algorithm revolutionized string matching by achieving linear time complexity, denoted as O(n). Introduced in 1970 by Knuth, Morris, and Pratt, this algorithm efficiently identifies patterns within text by employing a ‘Prefix Table,’ alternatively known as the LPS (Longest Proper Prefix which is also Suffix) Table. Unlike traditional methods, KMP avoids redundant comparisons, ...
Insertion sort is an important method in organizing data, especially good at sorting small groups of information. It works by dividing a list into two parts: one that’s already sorted and one that’s not. Just like when you sort playing cards, it takes each item from the unsorted section and finds the right spot for ...
In normal BFS of a graph all edges have equal weight but in 0-1 BFS some edges may have 0 weight and some may have 1 weight. For Example: A vector, d will be defined to store distances between different vertices from source(s). d[s] will be 0 as the distance from source to source is 0. s will be pushed into the front of the deque(q). We’ll visit connected nodes ...
