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.

Just check if size of s2, s3 is greater than zero before accessing the last element, i submitted your code with changes but it TLE'd on test 59. see this
So the problem is with the set. I thought it was something about the input. Thanks a lot.
