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 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.
