My solution is pretty much the same, except that I didn't want to accumulate as much memory (storing the entire grid can be pretty expensive in terms of memory) and used a bitset instead of hashtable for checking used values, since most of the time it's going to be full anyways, so hashtable only adds performance and memory overhead :) Print the value of the counter. It is a easy problem, one solution is to read all characters one by one and check if both are equal.
