use c++ screen shot the code and result, provide some explantions as well ty.

Q1. Write a function called reverse. It takes as a parameter a vector of int It returns a reference to a vector of int The function should: 1. invert the input vector 2. return a reference to the input vector Example std::vector vec {1,2,3); auto ret = reverse(vec); After this code, vec should contain (3,2,1) and ret should be a reference to a vector of int with values (3,2,1) There are no restrictions on how you can implement this function, but it should work with a vector of any size
