Efficient approach: Create a degree [] array of size 2 more than the length of the prufer sequence, since the length of prufer sequence is N – 2 if N is the number of nodes. Initially, fill the degree array with 1. the onion brewery barrington ilWebb8 dec. 2024 · For example,look at the following graph: Then following the algorithm we get something like: So,the Prufer sequence is ( 1, 8, 3, 1, 4, 4, 8).
