What is pattern recognition?

• Creating complex problems from small patterns

• Identifying similarities or patterns among small problems to solve complex problems more efficiently

• Ignoring patterns to solve complex problems

What is abstraction?

• simplification of a problem by removing details

• making a code more complex

• something only a computer can understand

• art work by Picasso

Why is pattern recognition important in computer science?

• It helps in solving complex problems more efficiently

• It makes problems more complex

• It slows down problem-solving

• It is not important in computer science

Which of the following is not done by abstraction?
