MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A Priori Analysis − This is a theoretical analysis of an algorithm. Efficiency of an algorithm is measured by assuming that all other factors, for example, processor speed, are constant and have no effect on the implementation. A Posterior Analysis − This is an empirical analysis of an algorithm.

Detailed explanation-2: -Algorithm analysis is an important part of computational complexity theory, which provides theoretical estimation for the required resources of an algorithm to solve a specific computational problem. Analysis of algorithms is the determination of the amount of time and space resources required to execute it.

Detailed explanation-3: -Posterior Analysis: It is done after the actual implementation and execution of the algorithm using any programming language like C, C++, Java, or Python. It is the actual analysis in which the space and time complexity of the algorithm is calculated more correctly.

Detailed explanation-4: -Posteriori analysis is a relative analysis. Priori analysis is an absolute analysis. It is dependent on language of compiler and type of hardware. It is independent of language of compiler and types of hardware. It will give exact answer.

Detailed explanation-5: -Analysis of algorithms is the determination of the amount of time and space resources required to execute it. Usually, the efficiency or running time of an algorithm is stated as a function relating the input length to the number of steps, known as time complexity, or volume of memory, known as space complexity.
