You can take a problem that might be relatively intuitive to solve but when you scale this thing up as is increasingly the case in the web, in large data systems, and so forth, you actually have to now think smart, you actually have to think efficiently and you have to solve this problem effectively.

你可以把一个问题用比较直观的方法解决,但如果你把此类问题的数量增大,正如越来越多的互联网，和大规模数据系统中出现的问题等等,你应该考虑怎样才能更简便，怎样才能更高效,你应该用行之有效的方法处理问题。

But it is in fact indicative of what's actually going on underneath the hood and for a forensic investigator to be honest and even problem set 5, it poses a potential wrinkle if those JPEGs, those photos we took are not contiguous back to back to back but are all over the place.

但是实际上就像那些法医调查员,所做的实质说明,其实对套题5也是如此，如果那些JPEG文件有问题，我们将其数据不能连续的,放回原来的地方，那么图像会呈现出波纹形状。
