Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Construct a bipartite graph with 5 vertices on one side and 3 on the other. Demonstrate whether a matching is possible based on the neighbor condition.

💡 Hint: Draw edges based on connections.

Challenge 2 Hard

Using Hall's theorem, evaluate a scenario where a group of 7 students is connected to exactly 5 tutors with specific matching pairs. Discuss if a complete matching exists or not.

💡 Hint: Check each student's connections before concluding.
