I can only edit line 18, the rest must remain as it is. The intName method in the "Problem Solving: Stepwise Refinement" section accepted arguments <1,000. Using a recursive call, extend its range to 999,999 . For example an input of 12,345 should return " twelve thousand three hundred forty five". Note that some number names may have extra spaces at the beginning or end..
