3.4.Maximum Profit Problem

[hamza]

Maximum Profit Problem

 

Write a function, with a array as a parameter, representing the monthly price of a certain good over a period of time. eg:

 

    Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec

{45, 38, 50, 48, 55, 64, 50, 30, 40, 42, 39, 52}

 

If you can buy and sell only once in the given period of time, find out the maximum possible profit  you can make, i.e.:

 

• Buy on Feb and sell on Mar you will make a profit of 50 - 38 = 12

• Buy on Apr and sell on Jun you will make a profit of 64 - 48 = 16

 

 

its not a homework keep in mind.

3. Users will not post their homework questions expecting to get their homework coded for them. If you have a question about part of the assignment that you do not understand, please post asking for an explanation rather than the code.

You didn't even bother rephrasing it. You just copied the problem in. We're not stupid. A lot of people here have been doing a lot of homework over many years so they are able to recognize homework when they see it.

 

There is a reason why students are assigned homework. It's because they are supposed to learn from solving the problem.

how i can belive you that i am not a school student.

its my interview question which iam not able to sort out

[Mchl]

Well... Ill give you these two min and max.

 

There's hardly anything more you need.

[Daniel0]

If they gave you a problem to solve as part of your interviewing process, it's because they want to asses your skills, not ours.

[Ken2k7]

Did you finish your interview? If so, I don't see why you can't ask for help, but please at least put some effort into solving it yourself and if you need help, post what you came up with, i.e.: your thoughts, and we can help further.
