Problem 1: Add all the natural numbers below one thousand that are multiples of 3 or 5. (Euler1.py)
Potential efficnecy improvements:
- Ignoring eveything divisble by 2
- Ignoring numbers below 4 (who cares?)
Notes: Can this be condensed to 1 line?
====== Problem 2: Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.
