The data structure developed for program 1 does not identify an indexOf method. This useful tool reports back the List index of the first item it finds that matches its input parameter. If it is not present in the List, the method returns -1. Write the indexOf method. You may (and should) use any of the public methods identified in the List interface under program 1 in your solution. Use Example: int main(){ List myList = new Linkedlist({1,2,3,4,5,7,9}); std::cout « "Index of 4: " « myList.indexOf(4) « std::endl; std::cout <« "Index of 310: " « myList.indexOf(310) << std::endl; } Dutput:

present in the List, the method returns -1.
Write the indexOf method. You may (and should) use any of the public methods identified in the List
interface under program 1 in your solution.
Use Example:
int main(){
List<int> my List
= new LinkedList({1,2,3,4,5,7,9});
std::cout <« "Index of 4:" « myList.indexof (4) <« std::endl;
std::cout << "Index of 310:
<« myList.indexof(310) <« std::endl;
}
Output:
