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.

This quiz covers the essential steps involved in the problem-solving process, from defining the problem to developing a functioning program. Key stages include problem specification, analysis, algorithm development, and implementation. Refresh your understanding of this crucial aspect of programming and system life cycles.
