Hi,

I am trying to solve this problem on codeforces: 126B - Password

However, my submitted code got RE on string with repeated characters like aaaa, www, ss, ... You could check the submission here: 97046351.

I don't know why the error arise. This is the first time I've encountered this kind of RE. Please help me with this.

Thanks in advance.

    So the problem is with the set. I thought it was something about the input. Thanks a lot.
