Introduction . The most important criteria in writing and evaluating the algorithm is the time it takes to complete a task. The duration of computation time must be independent of the programming language, compiler, and computer used. As you aware that algorithms are expressed using statements of a programming language. If a bulk of statements to be repeated for many numbers of times then subroutines are used to finish the task. Subroutines are the basic building blocks of computer programs. Subroutines are small sections of code that are used to perform a particular task that can be used repeatedly. In Programming languages these subroutines are called as Functions.
