c# How to loop and count back in another loop?

Hi,

Let's take a look at what you've done. 

You want to loop from the back of the list to the front, but i<Quoodown Count was used as a constraint for the for statement, so this loop obviously doesn't work properly. I have fixed the first loop for you, and it seems to work properly now.

var Quodown = new List<int>() { 9, 7, 6, 9, 7, 6, 4, 3, 0 };
double sumi = 0;
double avg = 0;

for (int i = 8; i > 0; i--)
{
    sumi += Quodown[i];
    Console.WriteLine("sumi:  "+ sumi);

    for (int y = i; y < 8; y++)
    {
        for (int z = Quodown.Count; z > 0; z--)
        {
            avg = sumi / z;
            Console.WriteLine(z);
        }
    }
}

Wishing you a pleasant programming experience!
