Answer 1

Answer:

A process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer is called Algorithm.

★ Characteristics of an algorithm:-

• Each of its steps, and their inputs/outputs should be clear and must lead to only one meaning.
• Input - An algorithm should have 0 or more well-defined inputs.
• Output - An algorithm should have 1 or more well-defined outputs, and should match the desired output.
