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 a non-empty array of decimal digits representing a non-negative integer, increment one to the integer.
The digits are stored such that the most significant digit is at the head of the list, and each element in the array contains a single digit.
You may assume the integer does not contain any leading zero, except the number 0 itself.
Example 1:
Example 2:
Example 3:
Constraints:
1 <= digits.length <= 100
0 <= digits[i] <= 9
将一个数字的每个位上的数字分别存到一个一维向量中,最高位在最开头,我们需要给这个数字加一,即在末尾数字加一,如果末尾数字是9,那么则会有进位问题,而如果前面位上的数字仍为9,则需要继续向前进位。具体算法如下:首先判断最后一位是否为9,若不是,直接加一返回,若是,则该位赋0,再继续查前一位,同样的方法,知道查完第一位。如果第一位原本为9,加一后会产生新的一位,那么最后要做的是,查运算完的第一位是否为0,如果是,则在最前头加一个1。代码如下:

我们也可以使用跟之前那道 Add Binary 类似的做法,将 carry 初始化为1,然后相当于 digits 加了一个0,处理方法跟之前那道题一样,参见代码如下:
