An algorithm is a defined process or set of rules for problem-solving, particularly within mathematics and computer science. It is characterized by specific criteria, including input, output, definiteness, finiteness, and effectiveness. These criteria ensure that the algorithm effectively handles computations and produces results after a series of steps.

2. Q: What Is An Algorithm? What are the criteria an algorithm must
satisfy or describe the characteristics of an algorithm.
Answers :
An Algorithm is a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer.
In mathematics and computer science, an algorithm is a step-by-step procedure for calculations. Algorithms are used or calculation, data processing,
and automated reasoning.
An algorithm is an effective method expressed as a finite list of well-defined instructions for calculating a function. Starting from an initial
state and initial input the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states,
eventually producing "output" and terminating at a final ending state.
 Criteria:
i. Input:
Zero or more quantities or quire should be inputted externally.
ii. Output:
At least one quantities should be produced.
iii. Definiteness:
Each instruction is clear and definite.
iv. Finiteness:
For n terms of cases the algorithm should terminate it’s process after n terms.
v. Effectiveness:
Must be very basic and feasible.
