Write a C++ function called reverse that takes in a string and returns its reverse - input: "top" output: "pot" Write a second C++ function called join that takes in two strings and reverse(or any other function), and returns a joined string of the reverse of the two inputted strings (or just whatever the function does). Pseudocode def join(string1, string2, function) return function(string1) + function(string2) input: "rob", "got", reverse output: "bortog" Use C++'s "std::function" to declare any functions
