10 Questions
What is the primary purpose of an algorithm in problem-solving with computers?
To provide a step-by-step procedure for solving a problem in a finite amount of time.
What is the main difference between a flowchart and a pseudo code?
A flowchart is a visual representation of an algorithm using symbols and arrows, while pseudo code is a textual representation of an algorithm using natural language and syntax similar to programming languages.
What is the advantage of using pseudo code over a flowchart when developing an algorithm?
Pseudo code is easier to modify and update, and it can be more easily translated into a programming language.
What is the purpose of debugging in the algorithm development process?
To identify and remove errors or bugs in the algorithm, ensuring it produces correct results.
How do algorithms contribute to the efficiency of computer programs?
Algorithms enable computers to perform tasks using the minimum amount of resources, such as time and memory, necessary to achieve the desired result.

Study Notes
Algorithm Basics
- The primary purpose of an algorithm in problem-solving with computers is to provide a step-by-step procedure for solving a problem or achieving a specific goal.
Flowcharts and Pseudo Code
- The main difference between a flowchart and a pseudo code is that a flowchart is a visual representation of an algorithm using symbols and diagrams, whereas pseudo code is a written representation of an algorithm using natural language and structured syntax.
- The advantage of using pseudo code over a flowchart when developing an algorithm is that pseudo code is often easier to modify and refine, as it does not require changes to the visual layout of the diagram.
Debugging
- The purpose of debugging in the algorithm development process is to identify and correct errors or bugs in the algorithm, ensuring that it produces the correct output and behaves as intended.
Algorithm Efficiency
- Algorithms contribute to the efficiency of computer programs by providing a clear, step-by-step procedure for solving a problem, reducing the amount of computational resources required to achieve a specific task.
- Efficient algorithms enable computer programs to complete tasks quickly and accurately, making them more productive and user-friendly.
