Hi, I am trying to configure an efficient algorithm (faster than O(n^2)) for sorting and pairing elements between 2 arrays.

The canonical Array difference example in Ruby is: [ 1, 1, 2, 2, 3, 3, 4, 5 ] - [ 1, 2, 4 ] #=> [ 3, 3, 5 ] What's the best way to get the following behavior instead? [ 1, 1, 2, 2, 3, 3, 4, 5 ].subtract_once([ 1, 2, 4 ]) #=> [ 1, 2, 3, 3, 5 ] That is, only the first instance of each matching item in the second array is removed ...
