Interesting Problem About Deleting Adjacent Characters in a Binary String
You're given a binary string. You can delete two adjacent characters however many times you like. Is it true that no matter how you delete adjacent characters, there is a unique shortest string that you can end up with?
I've been stuck on this for a while now. I suspect that the answer is yes, but I have no idea how to prove it. Please help me prove or disprove.
