You're right, I overlooked that.

You can also speed things up by noticing that the nodes[] and visited[] 
arguments never change, so getLongestPath can be made as a nested function with 
those arrays as locals in the enclosing function.

This will reduce stack consumption, improving cache performance, and nodeID will 
get passed in a register.
