Work Step by Step
Here’s the list in pairs:
Address Letter Next Pointer
32 B 33 → 30 (J)
30 J 31 → 38 (K)
38 K 39 → 36 (N)
36 N 37 → 40 (P)
40 P 41 → 34 (X)
34 X 35 → 46 (end)
So the list is: B → J → K → N → P → X
Remove N from the List
To remove N (at address 36), we need to:
Change the pointer at address 39 (K’s next) from 36 to 40 (P’s address)
Updated pointer:
39: 40
Now the list becomes: B → J → K → P → X
Replace N with G and Insert Alphabetically
We change the letter at address 36 from N to G.
Now we need to insert G in alphabetical order. The correct position is between B and J.
To do this:
Point 33 (B’s next) to 36 (G)
Point 37 (G’s next) to 30 (J)
Updated pointers:
33: 36
36: G
37: 30
Final Linked List
B → G → J → K → P → X
