Hi monks, I have a newbie question: I have four arrays, three contain lists of numbers, and the fourth contains pairs of numbers. For each pair of numbers in the fourth array, I want to find the two arrays that the pair of numbers come from (they might be from the same array).


# e.g. 
@array1 = (1,2,3,4,5);
@array2 = (6,7,8,9,10);
@array3 = (11,12,13,14,15);

#@array4 = (1,13,    # where 1 & 13; 5 & 6; 15 & 4 are pairs
            5,6,
            15, 4);

# i want to say that pair 1 & 13 are from array1 and array3

I know this is really easy but its getting me confused.

Hope you can help!
