I had a blast reading through the many creative and varied approaches to solving Problem #1. There's something very fun and enlightening about seeing the same problem solved in different ways:
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.
Look forward to seeing solutions in your language of choice!
