HELP! NWERC2016 — Driving in Optimistan???

Revision en1, by duckladydinh, 2017-11-16 21:44:13

Dear friends,

"Driving in Optimistan"

I have read this problem from last year to this year, but I am still unable to understand the example. The English is perfect. The way they express the problem is super nice, but it seems a little overwhelming for me. Therefore, can someone please help me clarify the sample input/output???

Thank you.
