Create a function that takes two numbers and a mathematical operator +, –, / , * and will perform a calculation with the given numbers.

Examples:

calculator(2, "+", 2) ➞ 4

calculator(2, "*", 2) ➞ 4

calculator(4, "/", 2) ➞ 2

Notes If the input tries to divide by 0, return: "Can't divide by 0!"

In python I want to create a singular function that takes two parameters 'head; and 'skip'. Head is a linked list. Skip is a non negative value. If skip is zero it should return the linked list unchanged. The skip amount determines the amount to skip over. I want to change the linked list accordingly and then return the linked list with the modifications, not a list. If you have a linked list 11 -> 12 -> 18 -> 20...

In C++, create a function exchangesl that takes an argument of an array of integers ( for C++ use implement void exchangesl(vector<int>& a) . Those integers need to be changed so that the smallest and largest values in the array are exchanged. Assume that there is at least one element, if the largest value occurs more than once then exchange the first instance, if the smallest value happens more than once then exchange the last instance.
