Comparing 2 arrays for a unique number

[caeanis]

That probably isn't worded right, but say I have 2 array, one holds 4 numbers (1 - 4)

The other Array has 3 numbers which range from 1 - 4. How can I scrub against the first list to find out which number the second array doesn't have?

 

I figured a for next loop but I can wrap my head around how to pull out the number that isn't matched...

You could loop over the items in the first array and do an Array.Index of against the other array until a match isn't found.

I figured out a way, thanks Plause!

 

I looped through one array nested inside the first. If I found a match I set the value in the in the first array to zero. I then looped through the first array and pull out the only value greater than zero.
