title: Algorithm for truck moving around a circle of gas stations
body: <p>You have a truck moving around a circular track with gas stations spaced out around the circle. Each station has a finite amount of gas. The gas tank on the truck is infinitely big. The distance between the gas stations requires a certain amount of gas to traverse. You can only move in one direction. </p>
  
  <p>What is the algorithm to use? 
  Which gas station do you start at? 
  Can you get all the way around and back to the start station?</p>
