Hi, Sorry I thought I had explained it. I want to remove just one copy of the duplicate pair e.g. one value from each array - it doesn't matter which array the values are removed from. I dont see how a hash would work - it would help extract the unique values in each array, but how could I use it to keep one copy of the duplicate values? Thanks!
