Graphs, as non-linear data structures comprising nodes and edges, represent relationships between entities. Three classic graph representation in data structure include Adjacency Matrix, Adjacency List, and Incidence Matrix. While Adjacency Matrix offers fast edge retrieval but consumes more space, Adjacency List is space-efficient but slower for edge retrieval. Incidence Matrix is rarely used due to its inefficient space utilization and slower ...
An infix expression is one that we use regularly. A single letter or operator followed by one infix string and another infix string makes up an infix expression such as A, A + B, and (A + B) + (C – D). Therefore, there are operators between operands in this. If the operator appears in an expression before the ...
Problem Statement Given a number n. Find the sum of the first n even natural numbers. Example Input : 4 Output : 20 Explaination The Sum of the first 4 natural numbers is 20 because 2+4+6+8 = 20 Constraints 1 <= N <= 10000 Approach 1: Naive Approach (Using a for Loop) This is the Brute-Force method to find the sum ...
A dictionary in data structure is used to store the data in the form of key-value pair. The dictionary in data structure has an attribute called the key. The key is the attribute that helps us locate the data or value in the memory. A dictionary in data structure supports a wide variety of operations using a wide ...
Searching refers to finding a sequence of various actions to find the solution to the problem in such a way that this sequence of actions solves the problem optimally by some criteria. The two major types of searching are Informed and Uninformed. Informed search uses problem definition as well as additional information about the guidance ...
The difference between algorithm and flowchart is simply that algorithm is the collection of rules that should be followed while solving any particular problem. flowchart is diagrammatic representation of the algorithm. What is Algorithm? Let’s understand what an algorithm is to clarify the difference between algorithm and flowchart. An algorithm is a method for solving a problem step by step. An algorithm is a set ...
Algorithm, pseudocode, and program are three related terms in computer programming. The difference between an algorithm and a pseudocode is algorithm is an informal representation of a solution to a problem whereas, a pseudocode acts as a bridge between an algorithm and a program. From the algorithm it is easier to convert into pseudocode and ...
The Difference Between BFS and DFS lies in their traversal methods. BFS explores nodes level by level, making it ideal for finding the shortest path. In contrast, DFS explores, as far as possible, each branch suited for topological sorting and detecting cycles. What is BFS? Breadth-First Search (BFS) is a vertex-based algorithm used to find the ...
Data Structures is a way to arrange data, and algorithms are the sequence of steps we would take to solve a given problem using those data structures. Data Structures and Algorithms (short for DSA) are an essential part of a programmer’s life; whether you are a Competitive Coder or a keen Developer, Data Structures are a ...
An algorithm is a step-by-step set of instructions, which are meaningful and used to solve any particular problem. To perform every process, there is a set of Algorithms, which lets us know how to proceed with the problem and solve it in some steps. The analysis of an algorithm is a technique that measures the performance of an ...
