The table given below gives portion of a linked list. Every list entry spans two consecutive address locations the 1st contains a letter of the alphabet, and the second contains a pointer to the next list entry.

Header 32

31 38
32 B
33 30
34 X
35 46
36 N

I need to figure how to alter the pointers in the table so that the letter N is skipped over and is no longer accessed in the list.

Then how do I replace the letter N with the letter G and alter the pointers so that the new letter appears in the list in its proper place in alphabetical order?
