The line is pasted in the end...
else if (b>i)
{
smallermatrix[a - 1, b - 1] = matrix[a, b];

}

I converted everything except for the line I have posted, I don't this that I would need to initialize a new array on each iteration ... ?!

I'm trying to convert the whole function from Jagged array into 2D array..

It's working now.
Thank you

I modified the post please check

Thank you so much, the problem is that result could be 2,3,4,5,6 or even 7 and it's not a fixed array, that's where I'm having a hard time :/
if my string is "test" then the function will take for example:
"te" and apply multiplication and return them to an array, then when I want to apply the function on "st" again, the results will overwrite the previous ones.
Every time I run the method/function, the array stores the values at the beginning of the array and I can see that clearly, but I'm not able to find a way that satisfies what I need...

Could you please explain more about the out parameter?
I have to assign it to a value before using it, and I'm really lost here

Thank you, I know that Thread, but I need to do it by myself :)
Any other tips?
