Split the input at each newline character to generate an array of strings
Coerce each string to a number
For each number, accumulate a number - starting at 0
  Add to the accumulating number the sum of that number and the current number divided by 3, rounded down, and decremented by 2
Return the accumulated number

Sub-routine: Recursive Fuel
- Accept a number as input
If the number is less than or equal to 0
  Return 0
Else
  Return the sum of the input number and the number returned from calling this sub-routine with the number resulting from dividing the input number by 3, rounding down, and decrementing by 2
