How do I find values and compare them in 2 arrays?

Hello guys! I need a little help, if someone can help me! :)

I use 2 arrays and i try to compare them.

ARRAY 1 (4,2,1)

---------------

0 = A,0

1 = B,0

3 = C,0

4 = D,0

ARRAY 2 (4,1,1)

---------------

0 = A

1 = C

3 = B

4 = C

So what means?

0 = Default

1 = Value exist in the same position for both arrays

2 = Value exist in different position

3 = Value not exist at all

So when check the example above will give us this result:

ARRAY 1 (4,2,1)

---------------

0 = A,1

1 = B,2

3 = C,2

4 = D,3

Some help please? Thank you!

Ah I understand better, you're describing different figure cases, and indeed case 2 is a bit more complex, what you can do is, instead of using For Each Element, use a For loop and use its loopindex to look through the values of the first array, and for each of these values, run another For loop through the second array, and if any of the values it contains is equal to array value at first For loopindex, stop the loop and trigger an event;

I guess an example would be easier to understand, I'll give it a shot once at home

Yes example will work better, to see the result.

But in the meantime i will try it myself.

Thanks again guys! :)

Also please note again:

Array 1 gives me this example:

0 = A,1

1 = B,2

3 = C,2

4 = D,3

And if you noted, in array2 below i use in position 4 same letter as position 1. But as result, array1 give me: 4 = D,3 (3 = value not exist)

0 = A

1 = C

3 = B

4 = C

* Of course letter "C" exist twice in array 2, but in array 1 we need it only 1. So array find first if the value = same position, otherwise find if exist to somewhere else or not exist.

In theory make sense, but i try to find a best solution.
