13 Fibonacci
Exercise 13 and Solution

Write a program that asks the user how many Fibonnaci numbers to generate and then generates them. Take this opportunity to think about how you can use functions. Make sure to ask the user to enter the number of numbers in the sequence to generate.(Hint: The Fibonnaci seqence is a sequence of numbers where the next number in the sequence is the sum of the previous two numbers in the sequence. The sequence looks like this: 1, 1, 2, 3, 5, 8, 13, …)

13 斐波那契
練習13 和解決方案

編寫一個程序，詢問用戶要生成多少斐波那契數字，然後生成它們。藉此機會考慮如何使用功能。請確保要求用戶輸入要生成的序列中的數字。（提示：Fibonnaci序列是數字序列，其中序列中的下一個數字是序列中前兩個數字的和。該序列看起來像這樣：1、1、2、3、5、8、13…）

14 List Remove Duplicates
Exercise 14 and Solution

Write a program (function!) that takes a list and returns a new list that contains all the elements of the first list minus all the duplicates.

Extras:

Write two different functions to do this - one using a loop and constructing a list, and another using sets.
Go back and do Exercise 5 using sets, and write the solution for that in a different function.
