Hi, Aamod, this is quite an interesting problem. I'll appreciate your clarification on test case 2. The toll pricing strategy that maximized the profit was stated as [10, 5, 0]. . Hence, for the given option and budget, the total profit will be 30. But a quick check shows that a toll pricing strategy of [5, 10, 0], which is valid for the given option and budget, also gives a total profit of 30. Unfortunately, the test suite assumes uniqueness of the profit maximizing toll strategy. In such situation, how are we to proceed? Thanks.
