For context, I was solving this problem: https://cses.fi/problemset/task/1701, and was wondering if we can decompose the two trees into their respective centroid trees, and then compare their Euler tour sequence for bijection.

Is it true for two trees, if their centroid trees are isomorphic, then the trees themselves are isomorphic too?
