Updated the code to track visited Nodes with Set data structure instead of Lists to bring down the lookup time in visited from O(N) to O(1)
as doing O(N) lookup each time in the visited List will become significantly slow when the graph grows

Name: Prime square remainders
Let pn be the nth prime: 2, 3, 5, 7, 11, ..., and
let r be the remainder when (pn−1)^n + (pn+1)^n is divided by pn^2.
For example, when n = 3, p3 = 5, and 43 + 63 = 280 ≡ 5 mod 25.
The least value of n for which the remainder first exceeds 10^9 is 7037.
Find the least value of n for which the remainder first exceeds 10^10.
