Given a String S, I want to find a string containing one lowercase letter and one uppercase letter for the alphabet.
If S = "aAbBcdEec", I want to get "aAbB" and "Ee".
And if S = "abcABCadD", I want to get "abcABC" and "dD".
I've been thinking of StringBuilder or Pattern as a way to solve this, but to no avail.
I don't even need code to solve this, can you guys give me a hint?
