Changed how the Visited nodes are tracked (#3811)
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

Add solution for Project Euler problem 123 (#3072)
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.

Reference: https://projecteuler.net/problem=123

reference: #2695
