14 (Stores 'm') 15 (Used as link)
16 (Stores 'a') 17 (Used as link)
18 (Stores 'r') 19 (Used as link)
20 (Stores 's') 21 (Used as link)
Numbers represented by circle are addresses of respective nodes. Here Front or Head has address 16. Which represents the Head Node.
Following image represents the word "smart" with respective nodes and their addressing.
Numbers represented by circle are addresses of respective nodes.
The head pointer is: 20
