Problem 1 Fibonacci Prime 18 points Write a program that determines the nth Fibonacci prime. Create a function that expects a natural number as argument. The function will calculate the nth number in the Fibonacci sequence (starting with 0 and 1) that is also a prime number. Create a second function that prompts a user to enter a positive number. If a negative number was entered, it prompts again until a positive number is entered. The entered number is returned by the function. Use both functions in the main to get a valid number n from the user, determine the nnumber and print it to the console. Example: Input: -7 Input (>0):-3 Input (>0): 4 4th Fibonacci prime: 13
