When it is required to remove the duplicate elements in a doubly linked list, a ‘Node’ class needs to be created. In this class, there are three attributes, the data that is present in the node, the access to the next node of the linked list, and the access to the previous node of the linked list.Below is a demonstration for the same −Example Live Democlass Node: def __init__(self, my_data): self.previous = None self.data = my_data self.next = None class double_list: def __init__(self): self.head = None ...

What is a palindrome?A palindrome is a string that is the same when read from left to right or from right to left. In other words, a palindrome string is the one whose reverse is equal to the original string.For example, civic, madam are palindromes.Cat is not a palindrome. Since its reverse is tac, which is not equal to the original string (cat).Write a program to find whether the input string is a palindrome or not.Method 1 - Find Reverse of the stringThe main thing required in the program is to find the reverse of the string.The reverse can be ...

When it is required to insert a new node in the middle of a doubly linked list, a ‘Node’ class needs to be created. In this class, there are three attributes, the data that is present in the node, the access to the next node of the linked list, and the access to the previous node of the linked list.Below is a demonstration for the same −Example Live Democlass Node: def __init__(self, my_data): self.previous = None self.data = my_data self.next = None class double_list: def __init__(self): self.head ...

When it is required to insert a new node at the end of a doubly linked list, a ‘Node’ class needs to be created. In this class, there are three attributes, the data that is present in the node, the access to the next node of the linked list, and the access to the previous node of the linked list.Below is a demonstration for the same −Example Live Democlass Node: def __init__(self, my_data): self.prev = None self.data = my_data self.next = None class double_list: def __init__(self): self.head ...

When it is required to insert a new node at the beginning of a doubly linked list, a ‘Node’ class needs to be created. In this class, there are three attributes, the data that is present in the node, the access to the next node of the linked list, and the access to the previous node of the linked list.Below is a demonstration for the same −Example Live Democlass Node: def __init__(self, my_data): self.prev = None self.data = my_data self.next = None class double_list: def __init__(self): self.head ...

When it is required to find the maximum and minimum values from a doubly linked list, a ‘Node’ class needs to be created. In this class, there are three attributes, the data that is present in the node, the access to the next node of the linked list, and the access to the previous node of the linked list.Below is a demonstration for the same −Example Live Democlass Node: def __init__(self, my_data): self.prev = None self.data = my_data self.next = None class double_list: def __init__(self): self.head = ...

When it is required to delete a node from the middle of a doubly linked list, a ‘Node’ class needs to be created. In this class, there are three attributes, the data that is present in the node, the access to the next node of the linked list, and the access to the previous node of the linked list.Another class needs to be created that would have an initialization function, and the head of the node would be initialized to ‘None’ inside this.Multiple methods are defined by the user to add node to the linked list, to display the nodes ...
