Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a sequence (6, 5, 4, 3, 2, 1), prove whether this is a graphic sequence using the Havel-Hakimi theorem.

💡 Hint: Calculate the sum to verify.

Challenge 2 Hard

Construct a simple graph from the degree sequence (2, 2, 2, 2).

💡 Hint: Ensure each vertex connects with exactly two others.
