Problem:
|
|
Each new term in the Fibonacci sequence is generated by adding the previous two terms.
|
|
0,1,1,2,3,5,8,13,21,34,55,89,..
|
|
Every third term from 0 is even So using this I have written a simple code
|
|
By considering the terms in the Fibonacci sequence whose values do not exceed n, find the sum of the even-valued terms.
|
|
e.g. for n=10, we have {2,8}, sum is 10.
