Quantity and Repetition of array

I'm new to Labview and would like some assistance please.

I need to count quantity of a each item with duplicates in both. Meaning, if I have a 2D array:

Quantity       Item

1                  Tomato
2                  Tomato
3                  Tomato
1                  Apple
1                 Orange

I would like the resulting table to be:

6                   Tomato
1                    Apple
1                   Orange

I've figured out how to count duplicates of a single column, but I can't figure out how to incorporate the Quantity into it.
