Separate word Regex Ruby

I have a bunch of input files in a loop and I am extracting tag from them. However, I want to separate some of the words. The incoming strings are in the form cs### where ### => is any number from 0-9. I want the result to be cs ###. The closest answer I found was this, Regex to separate Numeric from Alpha . But I cannot get this to work, as the string is being predefined (Static) and mine changes.

Found answer: Nevermind, I found the answer the following sperates alpha-numeric characters and removes any unwanted non-alphanumeric characters so anything like ab5@6$% =>ab 56

gsub(/(?<=[0-9])(?=[a-z])|(?<=[a-z])(?=[0-9])/i, ' ').gsub(/[^0-9a-z ]/i, ' ')

If your string is something like

str = "cs3232
cs23
cs423"

Then you can do something like

str.scan(/((cs)(\d{1,10}))/m).collect{|e| e.shift; e }
# [["cs", "3232"], ["cs", "23"], ["cs", "423"]]
