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.
Given two lists
A
andB
, andB
is an anagram ofA
.B
is an anagram ofA
meansB
is made by randomizing the order of the elements inA
.We want to find an index mapping
P
, fromA
toB
. A mappingP[i] = j
means thei
th element inA
appears inB
at indexj
.These lists
A
andB
may contain duplicates. If there are multiple answers, output any of them.For example, given
We should return
as
P[0] = 1
because the0
th element ofA
appears atB[1]
, andP[1] = 4
because the1
st element ofA
appears atB[4]
, and so on.Note:
A, B
have equal lengths in range[1, 100]
.A[i], B[i]
are integers in range[0, 10^5]
.这道题给了我们两个数组A和B,说是A和B中的数字都相同,但是顺序不同,有点类似错位词的感觉。让我们找出数组A中的每个数字在数组B中的位置。这道题没有太大的难度,用个HashMap建立数组B中的每个数字和其位置之间的映射,然后遍历数组A,在HashMap中查找每个数字的位置即可,参见代码如下:
