Best answer: Here's a cute Fibonacci trick you can try. It might give you an alternative way to get the answer, or a way to test your results after you've got the simple, boring approach working: double r5 = Math.sqrt(5.0); // square root of 5, used more than once double phi = (1.0 + r5) / 2.0; // the famous... show more
Best answer: Here's a cute Fibonacci trick you can try. It might give you an alternative way to get the answer, or a way to test your results after you've got the simple, boring approach working:

double r5 = Math.sqrt(5.0); // square root of 5, used more than once
double phi = (1.0 + r5) / 2.0; // the famous "golden ratio"

for (int i=0; i<=20; ++i) {
System.out.println(i + " : " + (long)( Math,pow(phi, i) / r5 + 0.5 ));
}

As you should see, the nth Fibonacci number is (φⁿ / √5) rounded to the nearest whole number, where φ=(1+√5)/2 is the Golden Ratio.

Another coding trick, less "mathy" this time, is to code the regular loop using:

int f0=0, f1=1; // Fib(n-1) and Fib(n) values when n=1

Then in the loop use:

f1 = f0 + f1;
f0 = f1 - f0;

...to advance f1 to become Fib(n+1) and f0 now be Fib(n). Cuts down on variables and eliminates the "shift" that you need to do using the "obvious" approach.

My question is, however, does the cache also store whatyou do on the website to an extent ? I know technically the cookie is responsible for saving your password, etc., but are your entries stored in the cache ? Does it keep some sort of trace ? For example, if you make a transaction, does your browser store your info in some way ? I d just like toget a vulgarized answer ! :)

• ### Are browser plugins processes or threads?

Best answer: Chrome and Firefox use separate processes for tabs, but I'm pretty sure plugins are threads, since they need to access the same memory space as the tab itself.

• ### Why do they call a search site an "engine", when it aint no engine?

An engine is in my car. And a spare in the trunk. And I guess I should count the one under the hood too.
