This accepted solution shouldn't be accepted, right?

I was looking at this problem A. Laptops and I found an accepted solution : https://mirror.codeforces.com/contest/456/submission/19548093.

but I don't see how it got accepted.

This solution shouldn't work for this testcase:

$$$ \\ 3\\ 1\;2\\ 2\;3 \\ 3\;4\\ $$$

Am I missing something here? Sorry if it's too noobish to ask.

Look at the constraints. $$$1 \leq a_i, b_i \leq n$$$. Your test case violates this constraint.

    Right! Thank you very much. I didn't realize constraint is the game changer here :p
