- জয়ের রাস্তার প্রতিটা পোকেমনেরই ঠিক দুটো করে শত্রু আছে।
- যেহেতু সে পরস্পর শত্রু এমন দুটো পোকেমন কখনোই ধরতে পারবে না, তাই সে যতই চেষ্টা করুক না কেন, জয়ের রাস্তায় সে সর্বোচ্চ \(n\)-টা পোকেমন ধরতে পারবে।
Cynthia loves Pokemon and she wants to catch them all. In Victory Road, there are a total of $50$ Pokemon. Cynthia wants to catch as many of them as possible. However, she can not catch any two Pokemon that are enemies with each other. After exploring around for a while she makes the following two observations:
- Every Pokemon in Victory Road is enemies with exactly two other Pokemon.
- Due to her inability to catch Pokemon that are enemies with one another, the maximum number of Pokemon that she can catch is equal to $n$.
