This is a letter for 2147C - Rabbits

Dear Problem C,

You tricked me. Oh, how you tricked me.

At first, you looked so innocent, like a “just a little greedy” problem. I thought, “Sure, just sum things up, maybe pick the max or min, easy peasy.” My heart skipped a beat of confidence.

But no. You were lying in wait. Each greedy step I took, you laughed. Each DP attempt, you smirked. Test 1 was fine, Test 2 was fine… and then Test 3 hit me like a ton of bricks. WA. My rating evaporated. My confidence? Shattered.

You looked like an easy greedy. You felt like a greedy. But inside, you had hidden rules, tricky orderings, and subtle catches that made my brain twist in ways I didn’t know were possible. Every time I thought I had you figured out, I found another trap.

Still, I can’t hate you. You taught me patience, observation, and the subtle art of thinking one step further than what seems “obvious.” You were a cruel lover, yes, but a beautiful one.

Problem C, you’re like that high-maintenance crush:

  • Appears simple at first glance

  • Secretly demands precision and care

  • Breaks my heart before giving any reward

  • And once solved, gives pure joy

I didn’t get you fully today, but I’ll be back. Next time, with sharper eyes and maybe a little extra caffeine. One day, I’ll AC you gracefully, and we’ll laugh together about all the WAs you gave me.

Yours, A hopeful (but exhausted) contestant

How many of you fell in love and heartbreak with Problem C like I did?

Just kidding the contest was awesome.

I built a graph with the positions with 0 and checked if it was bipartite (the color is the direction: left or right)
