## Description
|
||
|
|
<section id="description">给定正整数<code>num</code> ，返回小于或等于<code>num</code>的所有奇数Fibonacci数的总和。 Fibonacci序列中的前两个数字是1和1.序列中的每个附加数字是前两个数字的总和。 Fibonacci序列的前六个数字是<code>sumFibs(10)</code>和8.例如， <code>sumFibs(10)</code>应该返回<code>10</code>因为小于或等于<code>10</code>所有奇数Fibonacci数都是<code>sumFibs(10)</code>和5.如果卡住，请记得使用<a href="http://forum.freecodecamp.org/t/how-to-get-help-when-you-are-stuck/19514" target="_blank">Read-Search-Ask</a> 。尝试配对程序。编写自己的代码。 </section>
