Subtracting string arrays

[Brian Scott]

Hello,

I am having am issue subtracting two arrays with string elements.

I have the following?

a = ["StringA", "StringB", "StringC"]

b = ["StringC"]

How to I subtract the two arrays so I have a new array with the
following?

result = ["StringA", "StringB"]



Thanks

You've almost answered your own question:

a = ["StringA", "StringB", "StringC"] => ["StringA", "StringB", "StringC"]

?> b = ["StringC"]
=> ["StringC"]

a - b => ["StringA", "StringB"]
