This problem helps you practice core Computer Mathematics fundamentals in a practical way. It builds intuition around relation, reflexive, check. Let’s break it down step by step so you can implement it confidently.
Problem Statement
Given n and a list of pairs (a,b), check if relation is reflexive.
Input Format
n m then m pairs.
Output Format
YES or NO.
Constraints
1
Code Solution
This explanation is written for learning purposes and to help beginners understand the concept clearly.
Check whether all (i,i) pairs exist for i=1..n. Use a set of pairs.
Common Mistakes
- Misreading input/output format.
- Not handling constraints and edge cases.
- Off-by-one errors in loops.
- Forgetting to reset variables between test cases (if any).
