//Check N = 1.
//Check for needed longs.
//Use Long.parseLong() instead of Integer.parseInt().
//Use Long.MAX_VALUE instead of Integer.MAX_VALUE.
//Use an int array of ids instead of a boolean array of visited nodes during DFS.
//Declare a class variable instead of a method parameter, as passing by value could result in a TLE.
