When it is required to sort the elements of a circular linked list, a ‘Node’ class needs to be created. 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
The programming languages are used to give instructions to the computer in a language which a computer can understand.Computer languages are classified into three types as follows −Machine languagesSymbolic languagesHigh level languagesMachine languagesComputer is a machine. Since, its memory can store only 1’s and 0’s, instructions must be given to the computer in streams of 1’s and 0’s i.e. binary code.These are easily understandable by the machine.Programs written in binary code can be directly entered into computer for execution and it is known as machine language.Advantages of machine language include −Execution is very fast.It is very difficult to write and ...

When it is required to get the unique elements in a nested tuple, a nested loop and the 'set' operator can be used.Python comes with a datatype known as 'set'. This 'set' contains elements that are unique only.The set is useful in performing operations such as intersection, difference, union and symmetric difference.Below is a demonstration of the same −ExampleLive Demomy_list_1 = [(7, 8, 0), (0 ,3, 45), (3, 2, 22), (45, 12, 9)] print ("The list of tuple is : " ) print(my_list_1) my_result = [] temp = set() for inner in my_list_1: for elem in inner: ...

When it is required to multiply adjacent elements, the 'zip' method, the 'tuple' method, and the generator expression can be used.The zip method takes iterables, aggregates them into a tuple, and returns it as the result.Generator is a simple way of creating iterators. It automatically implements a class with '__iter__()' and '__next__()' methods and keeps track of the internal states, as well as raises 'StopIteration' exception when no values are present that could be returned.Below is a demonstration of the same −ExampleLive Demomy_tuple_1 = (7, 8, 0 ,3, 45, 3, 2, 22) print ("The tuple is : " ) ...

When it is required to check if a variable is a tuple, the 'type' method can be used. A tuple is an immutable data type. It means, values once defined can't be changed by accessing their index elements. If we try to change the elements, it results in an error. They are important contains since they ensure read-only access.The 'type' method checks to see the type of the iterable/value that is passed to it as an argument.Below is a demonstration of the same −ExampleLive Demomy_tuple_1 = (7, 8, 0, 3, 45, 3, 2, 22, 4) print ("The tuple is ...

When it is required to convert a string into a tuple, the 'map' method, the 'tuple' method, the 'int' method, and the 'split' method can be used.The map function applies a given function/operation to every item in an iterable (such as list, tuple). It returns a list as the result.The 'int' method converts the given data type to an integer type, if that operation is permitted.The split method splits the given data into different sections based on a delimiter or a default delimiter. The 'tuple' method converts the given data type into a tuple type.Below is a demonstration of the ... Read More
When it is required to add a dictionary to a tuple, the 'list' method, the 'append', and the 'tuple' method can be used.A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).The 'append' method adds elements to the end of the list.Below is a demonstration of the same −ExampleLive Demomy_tuple_1 = (7, 8, 0, 3, 45, 3, 2, 22, 4) print ("The tuple is : " ) print(my_tuple_1) my_dict = {"Hey" : 11, "there" : 31, "Jane" : 23} print("The dictionary is : ") ...

When it is required to chunk the tuples to 'N' values, list comprehension is used.The list comprehension is a shorthand to iterate through the list and perform operations on it.Below is a demonstration of the same −ExampleLive Demomy_tuple_1 = (87, 90, 31, 85, 34, 56, 12, 5) print("The first tuple is :") print(my_tuple_1) N = 2 print("The value of 'N' has been initialized") my_result = [my_tuple_1[i : i + N] for i in range(0, len(my_tuple_1), N)] print("The tuple after chunking is : ") print(my_result)OutputThe first tuple is : (87, 90, 31, 85, 34, 56, 12, 5) The ...
