Sorry, but I fail to understand your requirements. Do you have
a practical example?
Doing this without writing a loop or using arrays for memoizing
half-finished calculations:
public static int Foo(int[] input)
{ int result = 10;
for (int i = input.Length / 4; i >= 0; i -= 4)
{ int sum = 0;
for (int j = i; j < i +4 && j < input.Length; j++) sum +=
input[j];
sum *= i;
result = (result + sum) / 2;
}
return result;
}
To be honest, this is as artificial as it looks. When I look
again at my code, it seems that my main problem was that I have
not made a habit to input.Zip(Enumerable.Range(0, inputLength),
Tuple.Create) or similar when I need indexing in C# :).
I'm still interested in the answer, though.
