Josephus Problem, add one to method return.

gistfile1.rb

def josephus(count, skip)
  #catch errors
  return 0 if count == 1
  
  #base case
  return count-1 if skip == 1
  
  #generally calls base case
  if skip>count
    return (josephus(count-1,skip)+skip) % count
  end
  
  #eliminates numbers
  sub_count = count / skip
  rem = josephus(count-sub_count,skip)
  
  
  rem -= count % skip
  if rem<0
    rem+= count
  else
    rem+= rem/(skip - 1)
  end
  
  rem
end
