I Am Adding a New Code Snippet in an Existing Language

• I fixed Add Convex Hull in C #3295
• I named the pull request using Add {PROJECT} in {LANGUAGE} format

All output needs to match the project page. In general, all of the sample programs have a corresponding project page

See this for the test failures.

Thanks!

I have a good idea of how to navigate this now so I should be fine (I hope). I have a solution in place for all of the issues I was assigned, and I'm now refactoring and making sure it follows the project description to the letter.

I don't want to start over so I suspect each PR will have 1 or 2 failures before going through.

The tests are still failing. See this for details. Also, please review the project page again. The inputs are a list of X-coordinates and a list of Y-coordinates. The number of X- and Y-coordinates must be the same, and there must be at least 3 of them.

Something about your parsing algorithm is incorrect since there are errors like Invalid Integers for valid inputs. Please see this for details

[rzuckerm]

The parsing still isn't right. The usage error message is being shown for all the cases. See this

@2Clutch I used your parsing from Binary Search to fix this.
