Algorithm Design and Problem Solving Concepts

This video tutorial covers algorithm design and problem solving for IGCSE and O Level Computer Science. It explains the concept of computer systems and subsystems, emphasizing decomposition into smaller parts. Examples include a car's navigation system and an alarm clock. The video also discusses structure diagrams, flowcharts, and pseudocode as tools for illustrating solutions. Key concepts include inputs, processes, outputs, and storage, with practical examples to aid understanding.
