Ok, to be more simplest. Let's forget (just example to explain you) the second value after comma. So let's imagine we have 3 arrays.
Array1 = Question
Array2 = Answer
Array3 = Result
So, Array1 values start from 0 - Array1.width
This means, we start to detect from Array2:
Array2(0) -> Start detect each value to all position of Array1.
So from my latest example, Array1 have "E" to 1 position.
And our answer (Array2) "Ε" was in 0 position of Array2.
What means?
Array3 (or Array 1 after comma, whatever) will give us result: 2
I hope make sense now! If you check all my previous examples is exactly the same thing i try to explain all the time. Sorry for the misunderstanding.
And some fast examples:
Array1 => YES
Array2 => YES
Array3 => 111
Array1 => YES
Array2 => YSE
Array3 => 122
Array1 => YES
Array2 => NES
Array3 => 311
Array1 => YES
Array2 => ABC
Array3 => 333
This makes sense and I understood it as this and it was the results that my example gave but you said they were wrong and H should be 2 and E should be 3. Now you are saying E should be 2. There is confusion.
