$4\mathrm{.}13\mathrm{.}3$: Using a recursive call, extend the range of the intName method.

$541666\mathrm{.}3483534.$qx$3$zqy$7$

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 an extra space at the beginning and$/$or end.
