The Science of Computing Mystery Mania Six men: Bill Fox, Tom Smith, Robert Stevenson, Fred Edison, Larry Davis, and John Harrison were in a library together. Suddenly, the lights went out. When the lights came back on, Bill Fox was found shot. The other detectives have investigated; questioned the suspects, the witnesses, and people who know the suspects; and have collected physical evidence from the crime scene.

A light-year is a unit of astronomical distance that measures how far light can travel in one year, defined as 365.25 days, which is about 9.4507 * 10^12, or about 5.878 trillion miles. A parsec is a unit of astronomical distance, equal to about 3.26 light-years. One parsec corresponds to the distance at which the mean radius of the Earth's orbit subtends an angle of one second of arc. Since the numbers grow so large so quickly, it's often easier for astronomers to work with parsecs, and convert them back to light years, or even miles, when needed.  Write a function to convert parsecs to light-years.
