Algorithms Study Guide

Welcome to the study guide on algorithms! Algorithms are fundamental to computer science and play a crucial role in various applications. Whether you are a beginner or an experienced programmer, understanding algorithms is essential for writing efficient and effective code.

Basic Concepts

Before diving into specific algorithms, it's important to understand some basic concepts:

• Time Complexity: This measures the amount of time an algorithm takes to run as a function of the length of the input.
• Space Complexity: This measures the amount of memory an algorithm uses in relation to the length of the input.
• Big O Notation: This is a mathematical notation used to describe the upper bound of an algorithm's time or space complexity.

Common Algorithms

Here are some commonly used algorithms and their explanations:

• Sorting Algorithms: These algorithms arrange a list of items in a specific order. Common sorting algorithms include Bubble Sort, Selection Sort, Insertion Sort, Merge Sort, Quick Sort, and Heap Sort.
• Search Algorithms: These algorithms find a specific item in a list. Common search algorithms include Linear Search and Binary Search.
• Graph Algorithms: These algorithms work on graphs, which are data structures consisting of nodes and edges. Common graph algorithms include Dijkstra's Algorithm, Prim's Algorithm, and Kruskal's Algorithm.
• Dynamic Programming: This technique involves breaking down a complex problem into smaller subproblems and solving each subproblem only once.
• Greedy Algorithms: These algorithms make locally optimal choices at each step with the hope of finding a global optimum.
