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.
int x = 0;
int y = 1;
int limit = 4000000;
int result = 0;
int temp;
while (y<limit) {
temp = x + y;
x = y;
y = temp;
if (y%2==0) {
result += y;
}
}
System.out.println(result);
