Webb18 feb. 2024 · This can be used to show that Prüfer encoding is a bijection from trees with n vertices to sequences in { 1,..., n } n − 2 because: 1- from any sequence P in { 1,..., n } n − 2 you get a tree T on n vertices 2- the Prüfer sequence of T is P (we haven't quite proved this but is holds, you can test this on the example) Share Cite Follow Webb29 mars 2024 · Therefore, create an array degree[] of size 2 more than the length of the Prufer sequence. Initially, fill the degree array with 1. Iterate in the Prufer sequence and increase the frequency in the degree table for every element. This method works because the frequency of a node in the Prufer sequence is one less than the degree in the tree.
