Python program to create a Circular Linked List of n nodes and display it in reverse order
When it is required to create a circular linked list and display it in the reverse order, a 'Node' class needs to be created.To display the data elements in the circular list in reverse order, another method can be defined, that would reverse the data. 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 ...

Read MoreWrite a Python program to remove a certain length substring from a given string
We need to write a Python program which will remove a certain substring from a given stringAlgorithmStep 1: Define a string. Step 2: Use the replace function to remove the substring from the given string.Example Codeoriginal_string = "C++ is a object oriented programming language"modified_string = original_string.replace("object oriented", "")print(modified_string)OutputC++ is a programming languageExplanationThe in-build Python replace() function takes the following parameters:Oldstring: The string which you want to removeNewstring: The new string you want to replace in place of the oldstringCount: Optional. Number of times you want to replace the oldstring with the newstring
