DO IN PYTHON Write a decorator which wraps functions to log function arguments and the return value on each call.Provide support for both positional and named arguments (your wrapper function should take both*args and **kwargs and print them both):>>> @loggeddef func(*args):return 3 + len(args)..>>> func(4, 4, 4)you called func(4, 4, 4)it returned 66.

Write a function that gets a linked list of ints, and reverses it. For example - on input 1 -> 2 -> 3 -> 4, after the function finishes the execution, the list becomes 4 -> 3 -> 2 -> 1 - If the list has one element, then it doesn’t change - If the list is empty, then it doesn’t change You may use the data fields in the struct and the functions provided in LL.h and LL.c. // reverses a linked list void LL_reverse(LL_t* list); Test for the Function; void test_q3() { LL_t* lst = LLcreate(); LL_add_to_tail(lst, 1); LL_add_to_tail(lst, 3); LL_add_to_tail(lst, 8); LL_add_to_tail(lst, 4); LL_add_to_tail(lst, 3); LL_reverse(lst); intcorrect[] = {3,4,8,3,1}; inti; node_t* n = lst->head; for(i=0;i<5;i++) { if (n==NULL) { printf("Q3 ERROR: node %d==NULL unexpected\n", i); return; } if (n->data != correct[i]) { printf("Q3 ERROR: node%d->data==%d, expected %d\n", i, n->data, correct[i]); return; } n = n->next; } if (n==NULL) printf("Q3 ok\n"); } Support File…
In C In C, strings are implemented by a contiguous sequence of characters, terminated by NUL character, otherwise known as ASCII code 0 (10'). CAPI, provides a function stropy for copying strings. The prototype of the function is given in the following: char* strepy(char* destination, const char* source); A) Write your own version of stropy that receives two character pointers and copies the source string into the destination string, character by character, until it reaches a null character. • The function stops when it reaches the end of the string, in which case it makes sure the destination string is properly terminated. • The function returns the original destination pointer as its return value. • The function assumes that source and destination strings are valid pointers. • In case either source or destination pointers are NULL, the function simply returns NULL. B) Write a small program that demonstrates the use of your version of strepy() function. • Define a character array and…
Write a function f1 that takes the root of a binary tree as a parameter and returns the sum of the nodes which are the right child of another node. The root of the tree is not a child of any node. Consider the following class definitions while writing your code. Using c++ language. class Node {public:int key;Node* left;Node* right;};
Rewrite the below function, viral-growth in Racket, so that it can be passed to the below repeated function and so that the count variable of repeated (rather than a minsvariable in viral-growth) determines how many minutes of viral growth pass. Rewrite viral-growth to accept only one argument, the number of people who start the spread, and to return a lambda that accepts a list argument. (define (viral-growth ppl) (lambda (ls) [ YOUR CODE GOES HERE] (define (repeated f count) (lambda (x) (if (= count 0) x (f ((repeated f (- count 1)) x))))

Write a generic C++ function that finds the largest among the three values. Your function should have three parameters of the same type. Test the function with int, double, and string values.
This is in C++. Define a generic function called CheckOrder() that checks if four items are in ascending, neither, or descending order. The function should return -1 if the items are in ascending order, 0 if the items are unordered, and 1 if the items are in descending order. The program reads four items from input and outputs if the items are ordered. The items can be different types, including integers, strings, characters, or doubles. Example input bat hat mat sat 63.2 96.5 100.1 123.5 Ex output Order: -1 Order: -1 main.cpp #include <string>#include <iostream> using namespace std; // TODO: Define a generic method called CheckOrder() that// takes in four variables of generic type as arguments.// The return type of the method is integer // Check the order of the input: return -1 for ascending,// 0 for neither, 1 for descending int main(int argc, char* argv[]) {// Read in four stringsstring stringArg1, stringArg2, stringArg3, stringArg4;cin >> stringArg1;cin…
