Which core practice involves noticing common patterns to solve problems?

• A. Abstraction
• B. Decomposition
• C. Pattern recognition
• D. Algorithms

Answer: (C)

Noticing common patterns in problems is pattern recognition. This helps you solve new questions by spotting familiar structures and applying approaches that have worked before, rather than starting from scratch each time. In programming, you might recognize a pattern like looping through every item, counting occurrences, or searching for a match, and reuse the same reliable solution you’ve learned. Abstraction focuses on keeping only essential details, decomposition breaks a problem into smaller parts, and an algorithm is the specific step-by-step plan you follow; pattern recognition tells you when to apply a known approach by identifying those repeating structures.
