How hard is alchemy compared to other bronze problems?

Out of 1-10, 1 being the easiest bronze problem, 10 being the hardest bronze problem. What would you rate alchemy as?

USACO Rating - This website has the difficulties of all the USACO problems. According to this, at least, it’s top 5 in terms of difficulty, so judge it as you wish :stuck_out_tongue:.

It was one of the harder bronze problems. I had to use dfs + binary search to get AC.

it is one of the hardest

In contest, my naive solution got full points without too much work. For what it’s worth I spent 40 minutes on this one (mostly debugging my stupid mistakes), 10 minutes on counting liars, and 2 hours on photoshoot (problem 1 lmao).
