An algorithm in **Data structures and algorithm **is a
sequence of stepwise commands that explain how to perform something. When an
effective algorithm is written then it assists in breaking a problem down to
the smallest part. This also helps in thinking cautiously about the method in
which each part of the problem can be solved by coding.

An indispensable characteristic to
data structures is nothing other than *algorithms**.* Data structures can be applied by means of algorithms. An
algorithm is a process that one can use to write a function or program in any
other computer language.

**The major measures to compute the efficiency of an algorithm**

How effectively an algorithm uses time
and memory determines how effective it is. If an algorithm's resource
consumption, also known as computational cost, is at or below a predetermined
threshold, it is said to be efficient in the context of **data structures and algorithms**. Generally speaking,
"suitable" indicates that it will operate on a machine that is
available in a fair amount of time or space, usually based on the amount of the
input.

Time
complexity and space complexity are the two primary indicators of an
algorithm's effectiveness, although they cannot be directly compared. This
means that algorithmic efficiency takes time and spatial complexity into
account.

To
ascertain an algorithm's resource utilisation, an analysis of the algorithm is
required. The quantity of computer resources that an algorithm uses is referred
to as the algorithm's efficiency. As a result, the effectiveness of an
algorithm can be evaluated depending on how various resources are used. As
little resources as possible must be used for an algorithm to run as
efficiently as possible.

There
are 2 major methods to measure the efficiency of an algorithm in **Data structures and
algorithm**. The density of
an algorithm is separated into 2 kinds:

- Time
complexity
- Space
complexity

**Time complexity**

Different components are used to assess an
algorithm's time effectiveness. For instance, when creating a program for a
specified algorithm, one can run it in any programming language, and record the
overall execution time. The following variables could affect the execution time
that can be measured in this scenario:

·
Machine speed

·
Compiler in addition to other system Software devices

·
Operating System

·
The programming language that is used

·
Amount of data needed

On the other hand, to establish how resourcefully
an algorithm in **Data structures and algorithm** figures out a given issue, one would like to
establish how the implementation time is regarded by the quality of the
algorithm. Consequently, one has to create basic laws that resolve the competence
of a program with regard to the nature of the fundamental algorithm.** **

**Space
complexity**

Using larger storage space to solve a given
algorithm in less time or taking more time to solve a given algorithm in very
little space is known as a time-memory or space-time transaction. Numerous
different algorithms may be employed to tackle a particular programming
challenge. These algorithms could include both incredibly time as well as space-efficient
ones. A space/time transaction refers to a situation where one can speed up
programme execution at the expense of using less memory or where one can speed
up programme execution at the expense of using more memory.
