Possible bug in processing of solutions?


There seems to be something wrong with either the question or how the output is processed here.

Here’s my solution:

[ajaisingh@x1carbon ~]$ cat /tmp/y 
[ajaisingh@x1carbon ~]$ cat /tmp/y | tr -d $'\\!@#$%^&*()_\-+={}[];:\'\"`/>?.,<~|'

[ajaisingh@x1carbon ~]$ 

However, the same solution reports a different output online on the judge:


There isn’t even a \ in the input, I’m not quite sure what’s going on.
