Question

I have a array of 7 sets of data which are accessed through their indices 0-6. I need to use 6 for training and 1 for testing which need to be cycled until 7 combinations have been achieved like so.

Training – 0, 1, 2, 3, 4, 5
Testing – 6

Training – 1, 2, 3, 4, 5, 6
Testing – 0

Training – 2, 3, 4, 5, 6, 0
Testing – 1

….

Training 6, 0, 1, 2, 3, 4,
Testing – 5

The training data will be a queue of queues of ints and the testing is a queue of ints. My brain is fried I need to help desperately. I have resorted to simply hard coding them but it looks dreadful and if I want to change the amount of sets I have then it will require a rewrite.

A lot of answer using modulo!, I only used that for finding even numbers 🙂 i’m testing now if it works your all gettin upvotes

Lots of great answers!! you guys are the best! 😀

Answer 1

Modulo is your friend here.

for(int i = 0; i < set.Length; i++)
{
    for(int j = 0; j < set.Length - 1; j++)
    {
        // Do something with ... set[(i+j)%set.Length];
    }
    // Test with set[(i+set.Length-1)%set.Length]
}
