An algorithm is a step-by-step procedure for solving a problem or achieving a specific goal. Here are some of the key characteristics of algorithms:
Input: An algorithm takes input, which is processed to produce output. The input can be any kind of data, such as numbers, strings, or images.
Output: The output of an algorithm is the solution to the problem or the desired result. The output can also be any kind of data.
Definiteness: An algorithm must be precise and unambiguous. Each step of the algorithm must be well-defined and easily understood.
Finiteness: An algorithm must terminate after a finite number of steps. It cannot go on indefinitely.
Effectiveness: An algorithm must be effective, meaning that it must produce the correct output for any valid input in a reasonable amount of time.
Feasibility: An algorithm must be feasible, meaning that it must be possible to perform the required computations or operations with the available resources.
Generality: An algorithm must be general, meaning that it can be applied to a wide range of problems, not just to a specific instance of a problem.
Optimality: An algorithm should be designed to solve the problem in the best possible way, using the fewest resources or achieving the highest efficiency.
