Write the program to enter integer elements from user in singly linked list. User can enter both andeven values.

Here’s a simple program in Python that allows the user to enter integer elements into a singly linked list. The user can input both even and odd values.

# Node class to represent each element in the singly linked list
class Node:
    def __init__(self, data):
        self.data = data
        self.next = None

# Singly Linked List class
class SinglyLinkedList:
    def __init__(self):
        self.head = None

    # Function to insert a new node at the end of the list
    def insert(self, data):
        new_node = Node(data)
        if not self.head:
            self.head = new_node
            return
        last = self.head
        while last.next:
            last = last.next
        last.next = new_node

    # Function to display the linked list
    def display(self):
        current = self.head
        while current:
            print(current.data, end=" -> ")
            current = current.next
        print("None")

# Main program to use the SinglyLinkedList
def main():
    linked_list = SinglyLinkedList()
    
    # Taking input from the user
    n = int(input("Enter the number of elements you want to add to the linked list: "))
    
    for i in range(n):
        value = int(input("Enter an integer (even or odd): "))
        linked_list.insert(value)

    # Display the linked list
    print("The elements in the linked list are:")
    linked_list.display()

if __name__ == "__main__":
    main()

Explanation:

• Node Class: Represents each element in the linked list with a data field and a pointer to the next node.
• SinglyLinkedList Class: Contains methods to insert new nodes and display the list.
• Main Function: Interacts with the user, collecting integers and building the linked list, then displays the list.

Make sure to run this program in a Python environment, and it will allow you to enter integer elements into a singly linked list.
