What is the step by step method for solving an instance of problem?Select one:a.  Algorithmb.Complexityc.Analysisd.   Pseudo code

To solve the problem of selecting the correct option for solving an instance of a problem, let’s analyze the choices provided:

1. Break Down the Problem

We need to understand what each option represents in problem-solving contexts.

2. Relevant Concepts

• Algorithm: A step-by-step procedure to solve a problem or perform a task.
• Complexity: Refers to how the resources needed (time, space) grow with the input size; it doesn’t directly solve a problem.
• Analysis: The examination of algorithms or problems, typically involving assessing their efficiency and correctness.
• Pseudo code: A high-level description of an algorithm, using simplified programming language-like syntax.

3. Analysis and Detail

• Algorithm: This is fundamental for solving problems as it directly outlines the steps to reach a solution.
• Complexity: While it is important to consider when discussing algorithms, it does not serve as a method to solve a problem.
• Analysis: This is more about evaluating algorithms rather than solving a problem instance.
• Pseudo code: This helps in expressing the algorithm but is more of a means of translating the algorithm into code rather than the method itself.

4. Verify and Summarize

The option that directly represents the step-by-step method for solving a problem is an Algorithm, as it provides a clear outline for reaching a solution.

Final Answer

a. Algorithm
