A Prüfer sequence is a way to encode a labeled tree with \( n \) vertices into a unique sequence of length \( n-2 \). This sequence provides a convenient method for representing trees and has applications in combinatorics and graph theory. Here’s how a Prüfer sequence works: 1. **Definition of a Tree**: A tree is a connected acyclic graph. For \( n \) vertices, a tree has exactly \( n-1 \) edges.
