# Advantages and Disadvantages of Algorithm | Types, Properties, Steps, Benefits, Pros and Cons of Algorithm

Advantages and Disadvantages of Algorithm: To solve any problem or get an output, we need instructions or a set of instructions known as an algorithm to process the data or input. Basically used in calculations and data processing; thus it is for mathematics and computers.

It is a finite set of well-defined instructions that are followed to solve any problem.it is an effective method to solve the problem that can save time. Here we have to put input and after the processing, through the algorithm, we get an output. It is an easy method of determining the result within the time and space limitations.

An algorithm is a limited arrangement of successive guidelines that one ought to act to take care of a very much planned issue. Algorithms enjoy a lot of benefits. In PC programming, It is a succession of computational method that takes an assortment of components or values as info and produce an assortment of components or values as a result.

## What is an Algorithm? Advantages and Disadvantages of an Algorithm 2022

An algorithm is a set of instructions used for solving any problem with a definite input. This process defines the time taken to solve the given problem and also the space taken. This method is generally used in computers and mathematics to deal with the input or data and desired output.

An algorithm requires three major components that are input, algorithms, and output. In computers, an algorithm is very important when we want a specific set of instructions for performing a specific task that is definite. It works well in automated and high-frequency trending systems. Algorithms make people’s lives easier because they save slots of time for the things that are time taking if done manually. In an algorithm the problem is divided into parts then it becomes easy to understand every level of the process with logic.

### Types of Algorithms

There are many types of algorithms used to solve different types of problems which are as follows:

Recursive algorithm: In this algorithm, the process calls itself with small inputs repeatedly until the problem is solved. Here the subproblems are solved and automatically by repeatedly solving the subproblems complex problem are solved.

Brute Algorithm: Brute algorithm is the simplest way an algorithm can be planned to solve a problem. By brute algorithm, all the problems can be solved, and also every possible solution.

Backtracking algorithm: In this algorithm, it solves one problem if the problem doesn’t solve then it removes the step and again solves the same problem until it gets the solution. It is a recursive method but if the step does not give a solution then it does not repeat the same solution instead try to solve by the new method.

Divide and Conquer Algorithm: This is the most used algorithm as the name suggest first the problem is divided into smaller subproblems then it is solved and in the second part, it combines all the solution to solve the main problem.

Greedy Algorithm: In this algorithm, the solution is done part by part without considering the future and finding the immediate solution.

Dynamic Programming Algorithm: In this method, the problem is solved in small parts and saved for future use, and used for future problems.

### Properties of Algorithm

• Limit: A calculation ought to have a limited number of steps and it ought to end after a limited time.
• Input: A calculation might have many data sources or no contributions by any stretch of the imagination.
• Yield: It ought to result in no less than one result.
• Definiteness: Each progression should be clear, obvious and exact. There ought to be no equivocalness.
• Adequacy: Each progression should be straightforward and ought to take a limited measure of time.

Let us discuss some of the advantages of the algorithm, which are as follows

• Easy to understand: An algorithm is a stepwise solution that makes the program easy and clear. Thus this helps it be easy to read and understand.
• Debugging is easy: It makes the algorithm easier when it is solved step by step and makes it easy for the programmer to debug.
• Easy to manage: if we want to create a computer program, then making an algorithm help to create the program by making a flowchart after creating the algorithm.
• No programming language required: An algorithm does not come from any programming language thus it is very easy to understand and does not need any programming language knowledge.
• Can convert into the actual program: Since the process of breaking down the problem and solving it step by step in an algorithm make it easier to make an actual program.
• The procedure is predefined: The algorithm follows a definite procedure.

There are some disadvantages also of an algorithm, some are given below:

Time-consuming: It generally takes a lot of time to create an algorithm also for small problems. An algorithm usually takes more time than it is for solving simple solutions which does take much time.

Not for a complex problem: For solving a complex logic problem, an algorithm is not recommended as it cannot manage to solve to make understand the problem.

Subparts cannot be determined: While solving any problem in an algorithm, we cannot easily determine the small solutions that are understandable. Determining each part is difficult.
