The following table represents a portion

of a linked list in a computer's main

memory. Each entry in the list consists c

two cells: The first contains a letter of th

alphabet; the second contains a pointer

to the next list entry. Alter the pointers

so that the letter $\text{'}N\text{'}$ is no longer in the

list. Then replace the letter $\text{'}N\text{'}$ with the

letter $\text{'}G\text{'}$ and alter the pointers so that

the new letter appears in the list in its

proper place in alphabetical order.
