Study Notes
Problem Solving
- The problem-solving process involves defining, analyzing, and developing solutions for a problem.
- It begins with problem specification and ends with a functioning program.
- The steps include:
- Problem definition
- Problem analysis
- Algorithm development
- Coding
- Testing and debugging
- Documentation and maintenance
- The process of analyzing, designing, programming, implementing, and maintaining forms the life cycle of a system.
Problem Definition
- This step clearly defines the problem.
- Requirements are documented.
- Understanding the problem thoroughly is essential for efficient problem solving.
Problem Analysis
- Analyzing a problem involves recognizing the following:
- Inputs: The data used in the solution.
- Outputs: The desired results.
- Any additional solution requirements.
Algorithm
- An algorithm provides a step-by-step procedure for resolving a problem.
- The term originates from the 9th-century Arab mathematician, Mohammed Al-Khowarizmi, who developed methods for solving problems using specific step-by-step instructions.
Characteristics of an Algorithm
-
A well-defined algorithm must possess five characteristics:
- Input: An algorithm must accept one or more data items to be processed.
- Definite: Each step must be clearly defined and unambiguous.
- Effective: Each step, in theory, can be executed by a person using pen and paper in a finite number of steps.
- Terminate: An algorithm should always end after a finite number of steps.
- Output: An algorithm produces one or more results or outputs that represent the solution to the problem.
