Big number is a problem. Instead we can find the regular pattern in which those even and odd numbers appear. Then everything becomes simple and easy.
Gorgeously simple once you figure it out
hint: copy and paste the first few test suites into your MATLAB console and try plotting it with ':o'
My solution is working in my local computer but is not consistent with Test Suites starting from d = 100. I don't still get the answer.
You dont need generate all d fibonacci number to find the numbers of even.Think like that 2 odd fibonacci numbers will make a even number
like 1 1 make 2, and 3 5 make 8.So 3 numbers in group will have a even number
Not a hard problem at all lol
The Tran Tran comment is the key to solve the problem.
interesting - I never noticed the groups of 3
Funny problem lol
