Time complexity is a property of Problems someone might want to solve computationally, Algorithms designed to solve such problems and Programs implementing such algorithms. An abstract concept requires no installation or setup. Simply take any problem, algorithm, or code and ask "How lo...

echo "Hello, world!" Even in bash, this program works similarly in most other languages. The program has no input and will always function the same in an idealized world - run time should never change. Thus Hello World has constant complexity. Almost all elementary operations are assum...
