In our daily lives, we often follow step-by-step instructions to complete tasks, such as
following a recipe to cook a meal or a set of directions to reach a destination. These sequences
of actions are examples of algorithms in everyday life. Just as these instructions help

us achieve specific goals efficiently, algorithms in computer science provide a structured
approach to solving problems and performing tasks.

ALGORITHM

An algorithm is a set of instructions or steps in a specific order to solve a problem or to

complete a task. In other words, algorithms are the building blocks of computer programs
that comprise a sequence of operations to be performed by the computer in a specific
order to solve a problem.

CHARACTERISTICS OF AN ALGORITHM
An ideal algorithm has the following characteristics:

Precision: Each step is precisely defined.

Uniqueness: The result of each step can be uniquely identified and only depends on the
result of the preceding step.

Finiteness: It stops after a finite number of instructions are executed.

Well-Defined Input: The input to an algorithm must be clearly specified and precisely
defined.

Well-Defined Output: The output produced by the algorithm must also be clearly
specified and precisely defined.

Effectiveness: The algorithm should be efficient in terms of time and space.

USES OF AN ALGORITHM
