Hey -is-this-fft-, could you please recommend problems with similar coloring arguments if possible or some resource where I might be able to get a gist of it.

Hi, I am extremely thankful to you for taking the time again. I had wrongly read somewhere that the two centroids are similar and assumed that they should form isomorphic rooted trees. Thanks to you I understand my mistake now :))

Hey, thank you for taking the time and helping me. I am sorry if this may sound dumb but can you please explain what $$${P_4}$$$ and $$${P_6}$$$ are.

Hey, If there are two centroids, then aren't they adjacent and rooting them at any would result in 2 isomorphic rooted trees. So isn't it meaningless to check for each when we can choose any from the first and same for the second tree?
