PROBLEM

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.

ANSWER

4613732

JAVA CODE

public class Fibbonaci {

public static void main(String []args){

int pre=1;

int sum=0;

for (int i = 2; i <4000000; ) {

if(i%2==0)

sum+=i;

int tmp=pre;

pre=i;

i+=tmp;

}

System.out.println(sum);

}

}
