Simple problems resolved

Good morning!

I added the files with the solutions.
They were created in Visual Studio 2010.

Here is a print screen of the VS Solution if you want to reproduce it:

The UnitTests project needs a reference to the SimpleProblems project.

Thank you for your time.

In this case it is not necessary. The requirements of the problem states that the values range form 1 to N. Lowest possible index is 0. balauru pointed out that that I write defensive code without having a test for it. Seems to be the case also.

I guess I misunderstood the problems requirements "Try to work within the array without using any other temporary data structures.".

I will try to reply to the other comments.
