Overview of Algorithms
Algorithms are step-by-step procedures or formulas for solving a specific problem. They play a crucial role in computer science and programming, forming the backbone of software development and data processing. The study of algorithms encompasses their design, analysis, and implementation, which can be categorized into various types:
Types of Algorithms
1. Sorting Algorithms: These algorithms arrange data in a particular order (e.g., ascending or descending). Common examples include:
- Quick Sort
- Merge Sort
- Bubble Sort
2. Searching Algorithms: These are used to retrieve information stored within data structures. Examples include:
- Binary Search
- Linear Search
3. Graph Algorithms: These algorithms address problems related to graph theory, such as finding the shortest path or detecting cycles. Notable examples are:
- Dijkstra’s Algorithm
- Depth-First Search (DFS)
- Breadth-First Search (BFS)
4. Dynamic Programming: This approach solves complex problems by breaking them down into simpler subproblems. Examples include:
- Fibonacci Sequence
- Knapsack Problem
5. Greedy Algorithms: These algorithms build up a solution piece by piece, always choosing the next piece that offers the most immediate benefit. Examples include:
- Prim’s Algorithm
- Kruskal’s Algorithm
