Review Summary

I am approving your solution because your tests thoroughly cover the required behavior of getCoinCombination and match all specified examples from the task (1, 6, 17, and 50 cents) [CHECKLIST ITEMS #6–#9]. You also added thoughtful edge and additional cases (0 and 99 cents) that help confirm the greedy minimal-coin logic and ensure the function behaves correctly for boundary inputs, which strengthens confidence in the implementation. The Jest setup is correct, you import the function from the right file, and you respected the constraint of not modifying getCoinCombination.js [CHECKLIST ITEM #11]. There are no functional gaps or failing scenarios based on the given requirements, and all checklist items are satisfied. Nice work designing tests that are both requirement-driven and robust; this is a solid example of using unit tests to validate a greedy algorithm.
