# Exercise 1 - Sum of 3s and 5s
# Write a program which given the number N will sum all numbers
# dividable by 3 and 5 which are less or equal to N.
# N=10
# 1 2 3 4 5 6 7 8 9 10
# 3 + 5 + 6 + 9 + 10 = 33

# Exercise 2 - Factorial
# Write a program which will compute n factorial.
# n factorial denoted as n! is the product of all numbers less than
# or equal to n.
# 3! = 3 * 2 * 1 = 6
# 7! = 7 * 6 * 5 * 4 * 3 * 2 * 1 = 5040

# Exercise 3 - Reversed

# input: 6
# output:
# 1
# 1
# 2
# 3

# 8

# Ad 1.
# For each printed fibonacci number also print out the ratio of the
# current to the previous number.

# Exercise 6: Intersection

# numbers:
# a) present in both lists
# a) present only in first list


# Exercise 7: Fizz Buzz
# Write a program that prints the numbers from 1 to 100. For
# multiples of three print "Fizz" instead of the number and for
