What is an algorithm

algorithm is a step wise procedure.

1. What is an Algorithm ?

2. The word algorithm came from the name of a Persian author,” Abu Ja Far Muhammad bin Musa al Khwarizmi ”

3. Algorithm refers to a method that can be used by a computer for the solution of a problem.

4. What is an Algorithm ? An Algorithm is a finite set of instructions that , if followed , accomplishes a particular task.

5. Conditions that an Algorithm must satisfy: Input Output Definiteness Finiteness Effectiveness

6. Input: Zero or more quantities are externally supplied. Out put: At least one quantity should be produced. Definiteness: Each instruction is clear and unambiguous.

7. Finiteness: If we trace out the instructions of an algorithm, then for all cases the algorithm must terminate after a finite number of steps. Effectiveness: Every instruction must be very basic, so that it can be carried out by a person using only pencil and paper.
