1. Write a Python program that collects information about the user's four favorite books. The program should collect the name of the book as well as the year they were published. The program should create a tuple for each book in the following format: ('book name', 'published year'), and then add all of the tuples to a list. Finally, The program should display the name of the oldest book (based on its published year) (Tip: If two book were published in the same year, the program should only display one of them.)

2. From part 1, write a Python program to remove characters that have odd index values of the book.
