By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.

One Possible Solution: Java

public class Problem2 {
	public static void main(String args[]){
		int sum = 0;
		int a = 0;
		int b = 1;
		int c = a + b;
		while (c < 4000000){
			if (c % 2 == 0){
				sum = sum + c;
			}
			a = b;
			b = c;
			c = a + b;
		}
		System.out.println(sum);
	}

}

One Possible Soulution: Python

# Python version = 2.7.2
# Platform = win32

def fib(n):
    """Determines the sum of the even numbers in the fibonacci sequence
    up to value n"""
    thesum = 0
    a, b = 0, 1
    while a < n:
        if a % 2 == 0:
            thesum = (thesum + (a))
        a, b = b, a + b
    return thesum

def main():
    """The main program - calls the fib function and prints the value
    returned from the function --> x"""
    x = fib(4000000)
    print x
    
if __name__ == '__main__':
    main()

Find the sum of all the multiples of 3 or 5 below 1000.

I have been learning Java from internet tutorials, so I’m not real sure about this. If you see some code that can be improved on, feel free to leave a comment.

One Possible Solution: Java

public class Problem1 {
	public static void main(String[] args){
		int sum = 0;
		for(int counter = 1; counter < 1000; counter++){
			if(counter % 3 == 0 || counter % 5 == 0){
				sum = sum + counter;
			}else{
				continue;
			}
		}
		System.out.println(sum);
	}

}

One Possible Solution: Python

# Python version = 2.7.2
# Platform = win32

sum = 0
for i in range(1, 1000):
    if i % 3 == 0 or i % 5 == 0:
        sum = sum + i
print "Answer = ", sum

It started out OK, just dirt and ice for a trail. I decided not to wear my trackers, and just tread extra carefully on the icy spots. The farther up the mountain I went, the more snow was on the trail. I got all the way to the top (false summit) where it levels out and lost the trail. Several other people have also climbed it recently, and the most traveled path took the south ridge of Deer Mountain and I decided to follow it. It looked like the people who set out on this path new how to get to the top another way than the normal trail; however, after following it for about 10 minutes it all the sudden stopped and whoever made the trail just retreated back down the mountain. Someone else also started to trek where the trail should have been, but they also stopped after only about 50 yards. I could have gone on if I had my snowshoes on – although I am not sure I could have found the trail. So no-one has been to the top of Deer Mountain in recent days. It may be spring time when someone actually summits again, unless they can be a trailblazer and snowshoe through some deep snow, find the trail, then reach the summit. Who knows it may happen.

After getting stopped in my tracks, I just hiked back down the mountain. I had to take very small steps on the icy parts and still took a tumble or two, once falling about 5 yards down a hill and off the trail. It was good to get out in the Park on such a sunny day.

If you watch the slideshow, I contrasted the photos with some I took last July 4th when I climbed clear to the top. I tried to take a picture from approximately the same location as the last time I climbed – to show you a summer photo and a winter photo.
