To understand what is happening, you need to know what
arguments (i.e., the sequences of characters) the shell
is passing to strwrs.  I have modified Hwk3/strwrs to do
so (the arguments are enclosed in <....>); the previous
version is now Hwk3/strwrs.V0.

If this does not answer your question, please ask again.
