Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
History is littered with hundreds of conflicts over the future of a community, group, location or business that were "resolved" when one of the parties stepped ahead and destroyed what was there. With the original point of contention destroyed, the debates would fall to the wayside. Archive Team believes that by duplicated condemned data, the conversation and debate can continue, as well as the richness and insight gained by keeping the materials. Our projects have ranged in size from a single volunteer downloading the data to a small-but-critical site, to over 100 volunteers stepping forward to acquire terabytes of user-created data to save for future generations.
The main site for Archive Team is at archiveteam.org and contains up to the date information on various projects, manifestos, plans and walkthroughs.
This collection contains the output of many Archive Team projects, both ongoing and completed. Thanks to the generous providing of disk space by the Internet Archive, multi-terabyte datasets can be made available, as well as in use by the Wayback Machine, providing a path back to lost websites and work.
Our collection has grown to the point of having sub-collections for the type of data we acquire. If you are seeking to browse the contents of these collections, the Wayback Machine is the best first stop. Otherwise, you are free to dig into the stacks to see what you may find.
The Archive Team Panic Downloads are full pulldowns of currently extant websites, meant to serve as emergency backups for needed sites that are in danger of closing, or which will be missed dearly if suddenly lost due to hard drive crashes or server failures.
Your task is to calculate a b mod 1337 where a is a positive integer and b is an extremely large positive integer given in the form of an array.

这道题题让我们求一个数的很大的次方对1337取余的值,开始一直在想这个1337有什么玄机,为啥突然给这么一个数,感觉很突兀,后来想来想去也没想出来为啥,估计就是怕结果太大无法表示,随便找个数取余吧。那么这道题和之前那道Pow(x, n)的解法很类似,我们都得对半缩小,不同的是后面都要加上对1337取余。由于给定的指数b是一个一维数组的表示方法,我们要是折半缩小处理起来肯定十分不方便,所以我们采用按位来处理,比如223 = (22)10 * 23, 所以我们可以从b的最高位开始,算出个结果存入res,然后到下一位是,res的十次方再乘以a的该位次方再对1337取余,参见代码如下:

Pow(x, n)
