Whitespace, 73 bytes

Letters S (space), T (tab), and N (new-line) added as highlighting only.
[..._some_action] added as explanation only.

Since Whitespace inputs one character at a time, the input should contain a trailing newline so it knows when to stop reading characters and the input is done.

Outputs 0 for falsey, or nothing for truthy.

Try it online (with raw spaces, tabs and new-lines only).

Explanation in pseudo-code:

Start LOOP: Character c = STDIN as character If(c == '\n'): Stop program Character d = STDIN as character If(c == d): Go to next iteration of LOOP Print 0
