regex - Splitting string into pair of characters in Ruby

Question

I have a string (e.g. "AABBCCDDEEFF") and want to split this into an array with each element containing two characters - ["AA", "BB", "CC", "DD", "EE", "FF"].

Answer 1

Try the String object's scan method:

>> foo = "AABBCCDDEEFF"
=> "AABBCCDDEEFF"
>> foo.scan(/../)
=> ["AA", "BB", "CC", "DD", "EE", "FF"]
