When it is required to delete a node from 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 create a doubly linked list and display the elements in a reversed order, 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 reverse ...

When it is required to count the number of nodes 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.In a doubly linked list, the nodes have pointers. The current node would have a pointer to the next node as well as the previous node. The last value in the list will have ‘NULL’ value in the next pointer. It can be ... Read More

In this class, there are two attributes, the data that is present in the node, and the access to the next node of the linked list.In a circular linked list, the head and the rear are adjacent to each other. They are connected to form a circle, and don’t have ‘NULL’ value in the last node.Another ‘linked_list’ class needs to be created that would have an initialization function, and the head of the node would be initialized to ‘None’.Multiple methods ...

An expression is a combination of operators and operands.Operand is a data item in which operation is performed.An operator performs an operation on dataFor example; z = 3+2*1       z = 5Types of expressionsThe different types of expressions that are evaluated in C language are as follows −Primary expressions − The operand in this expression can be a name, a constant or any parenthesized expression. For example, c = a+ (5*b);Postfix expressions − In a postfix expression, the operator will be after the operands. For example, ab+Prefix expressions − In a prefix expression, the operator is before the operand. ... Read More
