"We know that surface use of dispersants decreases the environmental risk to shorelines and organisms at the surface and we know that dispersants break down over weeks rather than remaining for several years as untreated oil might."

I have used divide and conquer, as we seen before, to recursively break it into smaller problems. But the smaller problem of fib of 4 and the smaller problem of fib of 3 overlap with each other.

正如我们之前看到的，我已经进行了划分,并且递归性的把它分解为更小的问题,但是fib的简化问题,和fib的简化问题会相互重叠。
