On 4chan, a popular game is get. Every post on the site gets a sequential post ID. Since you can't influence or determine them, people try to guess (at least a part of) their own post number, usually the first few digits. Another version of the game is called dubs, and it's goal is to get repeating digits at the end of the number (i.e 1234555).
Your task, if you wish to accept it, is to write a program that takes a post id as input (standard integer, you can assume below 2^32), and returns how many repeating digits are on the end.
- Standard loopholes are disallowed.
- The program can be a function, full program, REPL command, whatever works, really, as long as no external uncounted code/arguments are needed to run it.
- Input can come from STDIN, function arguments, command line argument, file, whatever suits you.
