Q38. Design software for a vendor at a super market. If you give more amount for a bill, the vendor returns the change. The vendor gives change in efficient manner, say for example if Rs 250 were to be returned, he gives 2 notes of 100 Rs and 1note of 50 rupees. The program output should be such that an efficient number of denominations should be displayed. You have to take all the cases of available denominations and number of their availability. The program also should have an idea of asking 5 Rs from the customer, if available (for example, if amount to be given back is Rs 165 and if no denominations satisfy it, so that if customer gives 5rs you can return a 20 Rs note).
