Below you will find three questions. Answer each question in order with no spaces between them. So if the answer to the first question is a, the answer to the second question is b, and the answer to the third question is c then the solution is abc. There is no "trick", by the way. You can arrive at the solution through pure logic.

What is the third character (number, letter, or symbol) you will type to solve this?

How many different characters will you type to solve this?

What is the first character you will type to solve this?

1 Answer 1


The answer is

Any three-character string where the 1st and 3rd characters are the same (and are not 2) and where the 2nd character is 2 also works. So does 111.
I promise that I did not take hints from the comments before posting.
