Question

Write a menu driven program to do the following:

1. Create a linked list that contains 'n' number of Strings
2. Count the number of odd and even length strings in the list
3. In the linked list, if each string contains an odd number of length, remove the middle char
4. Display all the strings in the list

Answer 1

To complete the tasks described, a menu-driven program in Python can be implemented with a LinkedList class and methods for inserting nodes, counting odd and even length strings, removing middle characters, and displaying the list. The LinkedList class should handle edge cases properly for accurate results.

Step-by-step explanation:

Menu Driven Program for Linked List Operations

To write a menu-driven program that achieves the following tasks, we can use a programming language like Java or Python. Let's assume the use of Python for this example. The steps required in the program are:

1. Create a linked list containing 'n' number of strings.
2. Count the number of odd and even length strings in the list.
3. If a string in the linked list has an odd length, remove its middle character.
4. Display all the strings in the linked list.

Here's a conceptual overview of how this could be done in Python:

First, define a Node class representing a node in a linked list. Then, create a LinkedList class with methods to add nodes, count odd and even length strings, remove middle characters from odd length strings, and display the list. Inside the LinkedList class define methods like insert, remove_middle, count_odd_even, and display to perform the actions specified. Finally, create a menu function that allows the user to choose actions from the list of options provided.

The key part of the program is ensuring functions are correctly implemented to handle edge cases, like strings with odd lengths and maintaining the structure of the linked list after removal of a middle character.
