Return true if input is a Prime number
You are given n, a positive integer. Return true if n is a prime number, and false if it's not.
Find the middle node of a Linked List
Given a Singly Linked List, write an algorithm to find the middle node. You may not use more than one loop of any kind.
Graph Cycle Detection
You have a directed connected graph. Write an algorithm that detects any cycle, if one exists, and returns a list of its nodes.
