Challenge Problems

Push your limits with challenges.

Question 1

Construct a non-complete graph with vertex connectivity 2, edge connectivity 2, and a minimum degree of 2. Explain your reasoning.

💡 Hint: Ensure connectivity conditions are met while keeping it non-complete.

Question 2

Prove that for any simple graph with n vertices, the maximum degree is at least n-1.

💡 Hint: Use a connectivity argument to support degree calculations.
