MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Unambiguity: A perfect algorithm is defined as unambiguous, which means that its instructions should be clear and straightforward. Finiteness: An algorithm must be finite. Finiteness in this context means that the algorithm should have a limited number of instructions, i.e., the instructions should be countable.

Detailed explanation-2: -An algorithm is a sequence of unambiguous instructions for solving a problem, i.e., for obtaining a required output for any legitimate input in a finite amount of time [Levitin, p. 3].

Detailed explanation-3: -Algorithms have unambiguous operations It must be told to search for the smallest number, how to find the smallest number, how to compare numbers together, etc. The operation “Sort these numbers” is ambiguous to a computer because the computer has no basic operations for sorting.

Detailed explanation-4: -Clear and Unambiguous: The algorithm should be clear and unambiguous. Each of its steps should be clear in all aspects and must lead to only one meaning. Well-Defined Inputs: If an algorithm says to take inputs, it should be well-defined inputs. It may or may not take input.

Detailed explanation-5: -An algorithm should have the following characteristics − Unambiguous − Algorithm should be clear and unambiguous. Each of its steps (or phases), 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.
