Some kind of tech q?
You have to designa software for the vendor at super market. after calculating the bill, if you give more amount , he gives the change. he gives change in efficient manner ex if 250 were to be given back he gives 2 100 rupee notes and 1 50 rupees note.
The program output should be such that an efficient no of denominations should be displayed.
U have to take cases of available denominations and no of their availability. ( some times u have 3 20 rupees notes and no 50 rs). the program also should have an idea of asking 5 rs from the costomer if available ( if amt to be given back is 165 and if no denominations satisfy it, if cust gives 5rs you can give 20 rs note).
lastly some questions related to behaviour of mine with respect to old and new projects.
