change order of an array with another array

[ahhah]

I want to change the order of a 1D array based on another 1D array which specifies the order.  For example, I have an array which has the following items:  12, 13, 14, 15, 16.  And I have another 1D array which specifies an order of 3, 4, 0, 1, 2.  I want the resulting array to be 15, 16, 12, 13, 14.  How do I do this?  This should be really easy.  Another example, I'm given an array in the following order 1,2,3,4,5,6,7 and I have a order specifying array containing 0,6,1,5,2,3,4.  Therefore, the resulting array should be 1,7,2,6,3,4,5.  ???

This is, in fact, pretty easy.  Put an "Index Array" inside a for loop and wire the two arrays into it.  Disabled auto-indexing on the input array.  Wire the array element to the border of the for loop and you'll have the desired array.
