CCC 2012 Solutions

/*
  My actual solutions to CCC Junior 2012
  Dev-C++ was the IDE used, and its quirks
  led to some things that I would have preferred
  not doing (e.g. cout in a function instead of returning
  the value to be printed in the main function)

// Problem J5: No solution found. Only theoretical solution considered is very complicated
