来自主题: Linux版 - 在windows系统上安装emacs24
我用linux的主要原因是要用latex写文章和slides,emacs具有很多很多软件不具备的
优势,主要是lisp语言的支持,能做很多的智能选择,定义快捷键等,这里就不多说了
linux的主要问题是驱动和一些乱七八糟的问题,还有不能用office系列。如果能安装
emacs在windows上,可以说是一个完美的解决计划。
用下面的方法来安装,就能实现,不建议任何从源码编译的安装方法,太麻烦了。
第一步,安装miktex系统,这个就是latex所需要的所有软件包,很简单,只要等就可
以了,不过,建议你安装完整版本。
第二步,下载emacs系统的binary for windows,地址是

Category: containers Component type: type
Description
A vector is a Sequence that supports random access to elements, constant
time insertion and removal of elements at the end, and linear time insertion
and removal of elements at the beginning or in the middle. The number of
elements in a vector may vary dynamically; memory management is automatic.
Vector is the simplest of the STL container classes, and in many cases the
most efficient.

来自主题: JobHunting版 - leetcode做伤心了
1. 从四个边是O的位置开始,广度优先搜索相邻的位置是O的,并且标记为R. 这一步用
时O(n^2)
2. 把所有是R的位置标记为O,所有是O的位置标记为X,用时O(n^2)
因为输入是二位矩阵所有,O(n^2)时间复杂度是最好的了。 Java 代码 572ms跑完所有
test case
具体代码如下:
public void solve(char[][] board) {
if(board.length < 3) return;
Stack stack = new Stack();

for(int i = 0; i < board.length; i++){
if(board[i][0] == 'O'){
insert(stack, i, 0);
}

来自主题: StartUp版 - 如何电子签名?
最安全的肯定是用电子加密证书了,但是不是所有的人都会用,有人就喜欢白纸黑字的
签名。可现在大多数文档都是电子版的,每次打印下来,然后再签字,扫描,很麻烦。
俺做了些调查,发现两个方法,可以解决在PDF文件和WORD文件里面签字的问题了。
First, you need to create an image of your signature. You can write it on a
piece of paper, scan the page, and then crop the image file that your
scanner creates Save the image in one of the common image file formats, such
as .bmp, .gif, .jpg, or .png.

1. In Adobe Reader: File->Get Document Signed, then you will see "Sign Now",

上面这一楼贴了载止hw3b deadline时我match的结果(也就是老师可以以这些不match

1. 第一个题好像是用一个max-heap做的,就是每次从heap里pop出一个
pair(a[i]+b[j]),然后将 pair(a[i],b[j+1]) 和pair(a[i+1],b[j]) insert到heap里。
但好像需要check是不是重复的pair(a[i],b[j])已经在heap里了。
为避免重复,必须用 个变量J-Max track 目前max-heap中所有pair的最大的j. 如果j
< J_Max, insertpair(a[i+1],b[j])到heap里; 如果j = J_Max, 将 pair(a[i],b[j+1
]) 和pair(a[i+1
],b[j]) insert到heap里, update as J_Max = J_Max+1.
