The system need to implement the insertNode(), deleteNode() and displayList() functions. The insertNode() function is used to insert a new node of student record to the linked list. Assume that the input id is always unique, thus the linked list shall contain the student records with their respective id numbers are in ascending order. The displayList() function is used to display the list after inserting new node and/or after deleting a node. Please refer to the given structure definition shown in Figure 1, Your system interface should consider a few element such as user friendly, attractive and appropriate word. You may add more suitable data in the structure but limited to not more than 3. The deleteNode() function is used to remove a record of the targeted id from the linked list.
