Definition and Characteristics

• Finiteness: An algorithm must terminate after a finite number of steps.
• Well-defined: Each step must be clear and unambiguous.
• Effectiveness: The steps should be basic enough to be performed, in principle, by a person using only paper and pencil.
• Generality: An algorithm should be applicable to a broad set of problems, not just a single instance.

Types of Algorithms

• Sorting Algorithms: Such as QuickSort and MergeSort, which arrange data in a specific order.
• Search Algorithms: Such as Binary Search, which efficiently finds an item in a sorted list.
• Graph Algorithms: Such as Dijkstra's algorithm, used for finding the shortest path in a graph.
• Dynamic Programming Algorithms: Which solve complex problems by breaking them down into simpler subproblems.
