Algorithm:- An algorithm is a finite set of instructions
that, if followed, accomplishes a particular ta
In addition, all algorithms must satisfy the following criteria:
Input: zero or more quantities are externally
supplied.
Output: At least one quantity is produced.
Definiteness: Each instruction is clear and unambiguous.
Finiteness: if we trace out the instructions of an
algoritm, then for all cases, the algorithm terminates after a finite number of
steps.
Effectiveness : Every instruction must be very
basic so that it can be carried out , in
principle, by a person using only pencil and paper . it is not enough that each
operation be definite as in criterion 3; it is also must be feasible.
