You seem to be confusing a string pointer (which is just
a char*) with a string (which is a block of storage that
contains a sequence of characters followed by a null
character).

The char** argument to remD() is the address of a char*
variable to which is assigned the value of the string
pointer at the head/top of the Deque.  No new strings
(i.e., blocks of storage containing null-terminated
strings) need to be created.

Again, you setting a char* to the pivot string pointer,
which does not require creating a string.
