What is an algorithm? A sequence of unambiguous instructions
for solving a problem, obtaining a
required output for any legitimate input in
a finite amount of time.

What does 'finiteness' mean in It means the algorithm terminates after a
the context of algorithms? finite number of steps.
Define 'definiteness' in It refers to the instructions being
algorithms. rigorously and unambiguously specified.
What is meant by 'input' in an Valid inputs are clearly specified for the
algorithm? algorithm.
What does 'output' signify in The algorithm can be proved to produce
an algorithm? the correct output given a valid input.
Explain 'effectiveness' in the It means the steps of the algorithm are
context of algorithms. sufficiently simple and basic.

Why is studying algorithms They are the core of computer science
important? and provide a toolkit for practitioners to
design and analyze algorithms for new
problems.
