Ah, good idea - I'll give it a shot - thanks again for taking the time to respond, much appreciated :)

Hey Zruf - thanks for the resposne
Without giving too much away - How can I make this more efficient then?
I would have thought a nested for loop wouldn't be that impactful and on a similar Kata a nested for loop worked fine.
Also the code above shouldn't be printing two times? The System.Console.writeline is commented out so it only ever "returns" - not sure why it would be printing twice

I may be misunderstanding the question - but you do know the contents of the array, as this is passed into the function you are making.

Arrays can be accessed in most languages like so - assumeing I have an array called "MyArray"

MyArray[0] - this would grab the first value of the array, MyArray[2] would grab the 3rd and so on.
You can find the length of the array in - for example C#, by using MyArray.Length

So with this in mind, you should be able to loop through an array and find the max sum

I agree with the poster above me - it would help to draw an array on a piece of paper, and figure out how you would do this manually.
