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.
