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 the input value, find the sum of the even-valued terms.
I wanted to use : z = feval(symengine,'numlib::fibonacci',10)
to get the 10th element for example but CODY returns:

pas de chance!
You should add test cases where x or x+1 equals an even fibonacci number (either small or large).
Nice problem. I always have problem with big numbers.
I solved the problem until x = 4000000 but x = 97455000 it gives me an error of exceeding the memory(overflow) because the number is too large.
y is it not working when it even works on octave and get results in a sec

those test numbers are too big
it is correct but by server error its not showing
test for cheating
OK, I gamed this one so it only works up to about 1 billion. I wanted to see everyone else's interesting solutions.
this trick (c.f. Solution 26456) works only for these particular test cases, it would fail for example with euler002(6)...
