Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Create a strategy for finding disjoint groups among any set of ages, where you are given distinct ages ranging from a different minimum to a maximum.

💡 Hint: Break down ages into pairs and work through combinations.

Challenge 2 Hard

If there are 12 students aged 18-60, how would you utilize the pigeonhole principle to confirm shared sum age groups?

💡 Hint: Iterate through subsets systematically.
