1. Replace the incorrect implementations of the functions below with the correct ones that use recursion in a helpful way. You may not use the c++ keywords: for, while, or goto also, you may not use variables declared with the keyword static or global variables, and you must not modify the function parameter lists. Finally, you must not create any auxiliary or helper functions. // str contains a single pair of angle brackets, return a new string // made of only the angle brackets and whatever those angle brackets // contain. You can use substr in this problem. You cannot use find. // // Pseudocode Example: // // // // string findAngles (string str) { } findAngles ("abc 789") => " " findAngles (" 7") => " findAngles ("4agh ") => " " return "*"; // This is incorrect.
