1. Help exercise!

I have a home work. I don't understand. Can you help me?

Subject: Given an amount of money (less than 10,000VND), compute the number coin of 500VND, 1,000VND, 2,000VND, 5,000VND needed. Remember that the number of coin is minimized.

3. Yes.I don't understand and I can't doing it. Can you help me!

4. I did not ask if you did not understand, since that was clear. I asked what it was that you did not understand.

5. i don't understand algorithm

6. Ah. If you want to "cheat", search the Web for "greedy algorithm". If you want to try to come up with an algorithm yourself (and you should), get some coins of different denominations, come up with some amount at random that can be made up of your coins, then try out systematic ways of solving the problem. When you have found one, implement it.

7. Can you help me code it exercise?

Nono, you wrote up an exercise for yourself that you didn't understand how to do.

11. It doesn't matter if the assignment was given to you by a teacher, or you found it from a book. The point of doing exercises is that you try to figure out things for yourself.

Try it out with some sums and think how you came up with the answer.

For example, if the sum is 9500 VND, then the coins you are looking for would be 1 x 5000, 2 x 2000 and 1 x 500.
