What is a good algorithm?
Input: a good algorithm must be able to accept a set of defined input.
Output: a good algorithm should be able to produce results as output, preferably solutions.
Finiteness: the algorithm should have a stop after a certain number of instructions.
Generality: the algorithm must apply to a set of defined inputs..
What is pseudocode and flowchart?
Flowcharts are written with program flow from the top of a page to the bottom. … The following shapes are often used in flowcharts: Pseudocode is a method of describing computer algorithms using a combination of natural language and programming language.
What are examples of algorithms?
A step-by-step solution. Each step has clear instructions. Like a recipe. Long Division is another example of an algorithm: when you follow the steps you get the answer.
What are three algorithms?
There are three basic constructs in an algorithm: Linear Sequence: is progression of tasks or statements that follow one after the other. Conditional: IF-THEN-ELSE is decision that is made between two course of actions. Loop: WHILE and FOR are sequences of statements that are repeated a number of times.
Who invented pseudocode?
The word is derived from the phonetic pronunciation of the last name of Abu Ja’far Mohammed ibn Musa al-Khowarizmi, who was an Arabic mathematician who invented a set of rules for performing the four basic arithmetic operations (addition, multiplication , subtraction, and division) on decimal numbers.
What is pseudocode and algorithm?
An algorithm is a sequence of steps which is utilized in order to solve a computational problem whereas pseudocode is nothing but a more simple form of an algorithm which involves some part of natural language to enhance the understandability of the high-level programming constructs or for making it more human-friendly …
What is the difference between algorithm pseudocode and flowchart?
The main difference between Pseudocode and Flowchart is that pseudocode is an informal high-level description of an algorithm while flowchart is a pictorial representation of an algorithm. … Thus, pseudocode and flowchart are two methods of representing an algorithm.
Can every problem be solved with an algorithm?
Well, an algorithm is a sequence of steps that solves a problem. With that definition (and in fact most definitions of algorithm) any computer program is also an algorithm. Every Euler problem can be solved with a computer program, so the answer is yes.
How do you use pseudocode algorithm?
Writing pseudocode is pretty easy actually:Start with the algorithm you are using, and phrase it using words that are easily transcribed into computer instructions.Indent when you are enclosing instructions within a loop or a conditional clause. … Avoid words associated with a certain kind of computer language.Feb 7, 2019
How do you write a good algorithm?
There are many ways to write an algorithm….An Algorithm Development ProcessStep 1: Obtain a description of the problem. This step is much more difficult than it appears. … Step 2: Analyze the problem. … Step 3: Develop a high-level algorithm. … Step 4: Refine the algorithm by adding more detail. … Step 5: Review the algorithm.
Is flowchart a pseudocode?
Flowcharts and pseudocode often have the same level of expressiveness, but differ in linearization. Pseudocode is linear (i.e. a sequence of lines with instructions), a flowchart is not. Therefore, flowcharts are a higher abstraction level, used before writing pseudocode or for documentation.
How do I check pseudocode?
The only real way to “test” a pseudocode would be to dry-run it by hand which has some limitations of human prone errors. Try to see what real programming language most resembles the pseudocode you write and convert it into a legal program. Running it through a legal compiler would solve your problem then.
Is there any difference between algorithm and pseudocode?
An algorithm is defined as a well-defined sequence of steps that provides a solution for a given problem, whereas a pseudocode is one of the methods that can be used to represent an algorithm.
What is a pseudocode with example?
Pseudocode is an artificial and informal language that helps programmers develop algorithms. Pseudocode is a “text-based” detail (algorithmic) design tool. The rules of Pseudocode are reasonably straightforward. All statements showing “dependency” are to be indented.
What are the 3 algorithm constructs?
Computer scientists have defined three constructs for a structured program or algorithm. The idea is that a program must be made of a combination of only these three constructs: sequence, decision (selection) and repetition (Figure 8.6). It has been proven there is no need for any other constructs.
Is a flowchart an algorithm?
Algorithm and flowchart are the powerful tools for learning programming. An algorithm is a step-by-step analysis of the process, while a flowchart explains the steps of a program in a graphical way. Algorithm and flowcharts helps to clarify all the steps for solving the problem.
What is difference between program and algorithm?
A computer program is a specific sequence of instructions in a specific programming language. A program may contain the implementation of many algorithms. … An algorithm is a self-contained step-by-step set of operations to be performed to solve a specific problem or a class of problems.
Is Python a pseudocode?
Pseudocode is a way of expressing an algorithm without conforming to specific syntax rules. … Now you are going to have a look at a simple pseudocode example and see the equivalent code in both Scratch and Python. You could adapt this to help your students learn to translate between pseudocode, Scratch, and Python.
What is the use of pseudocode?
Definition: Pseudocode is an informal way of programming description that does not require any strict programming language syntax or underlying technology considerations. It is used for creating an outline or a rough draft of a program.
What is basic algorithm?
Algorithm is a step-by-step procedure, which defines a set of instructions to be executed in a certain order to get the desired output. Algorithms are generally created independent of underlying languages, i.e. an algorithm can be implemented in more than one programming language.
How do you write an efficient algorithm?
How to write code efficientlyCreating function. … Eliminate unessential operations. … Avoid declaring unnecessary variables. … Use appropriate algorithms. … Learn the concept of dynamic programming. … Minimize the use of If-Else. … Break the loops when necessary. … Avoid declaring variables in the global scope.More items…•Aug 19, 2020
