Problem Solving in computer science involves analyzing a problem, designing a solution, and implementing it effectively. It is the process of breaking down complex problems into simpler, manageable parts and finding an optimal way to solve them. Good problem-solving skills are crucial for writing efficient and effective software.

Algorithm is a step-by-step procedure or formula for solving a problem. It outlines a set of instructions that are followed to achieve a specific task or solve a problem. Algorithms are designed to be efficient, meaning they solve problems in the least amount of time and with minimal use of resources. Key aspects of algorithms include correctness, efficiency, and simplicity. Common algorithmic techniques include sorting, searching, and dynamic programming. Understanding algorithms is essential for optimizing problem-solving strategies in computing.
