Description: ACM的一道题(关于全排列的)
题目是：
5009 ArrangementTimeLimit : 1 Second Memorylimit : 32 Megabyte
Totalsubmit : 414 Accepted : 176
Given a string of letters(A-Z),your task is to arrange them in alphabetic order.
Following is an example:
A string "BAC" contains 3 letters B,A and C,you should output
ABC
ACB
BAC
BCA
CAB
CBA
In the output file.
A string may contain several letters same,for example "BBC" you should output like this:
BBC
BCB
CBB
Input
The first line of input contains a single integer t, the number of test cases,followed by the input data for each test data.Each test case is a string of n(1<=n<=26) letters.

Description: 1.该产品是一个民用高速脱水机，机器最大容量为5公斤。
2.全自动波轮洗衣机的脱水转速为：8000-1000rpm。当脱水转速到达3200rpm时，化纤类衣物在夏天几乎可以直接穿了——非常干了。
3.该产品原来是德国的，他们采用交流感应电动机，我们无法实现——因为没有解决刹车的问题。高速下刹车的解决需要好的材料选择以及精确的设计。BLDC的刹车就好办了。
4.我的设计非常精简——1片MEGA48，6只75NF75，1只20A的桥——详细见电子元器件清单，成本只有不足30元。
5.请务必采用环形变压器！因为借助它的压降来分析的
6.同时提供的PCB以及电子元器件清单都是真实的，可以直接用（PCB上低端驱动中的一个三极管需要改为PNP！）-1. The product is a commercial high-speed dehydration machine, the machine maximum capacity of 5 kg.
2. Automatic Washing Machine for the dehydration speed :8000-1000rpm. When the dehydration speed reaches 3200rpm, the chemical fiber clothing to wear in the summer is almost directly- and very dry.
3. The product was originally German, and they use AC induction motor, we are unable to achieve- because there is no brake to solve the problem. High speed brakes to resolve the need for good material selection and precision design. BLDC brake on the easier to handle.
4. My design is very streamlined- 1 Pian MEGA48, 6 Zhi 75NF75, 1 Zhi 20A of the bridge- see detailed list of electronic components, costs less than 30 yuan.
5. Please be sure to use ring transformer! Because through it, the pressure drop to the analysis of
6. Also provides a list of PCB and electronic components are real and can be directly (PCB on the low-side driver transistor need to be changed in a PNP!)

Description: JPEG 静态图像压缩
各文件功能说明如下：
1) JPEG压缩程序：gendat.exe
2) 为压缩后的数据加上JPEG文件头的程序genjpg.exe
3) 解JEPG压缩程序extrdat.exe
其中：（1）的输入参量是需要生成的压缩文件的名字。
主程序流程为：
a) 程序初始化，读取文件名称、原始图像数据等基本数据；
b) 从AC.TAB和DC.TAB两个文件生成AC表和DC表，存入数组
c) 以8×8为样本单位进行DCT变换
d) 以8×8为样本单位进行量化
e) 以8×8为样本单位进行Z形扫描
f) 以8×8为样本单位进行熵编码
g) 以8×8为样本单位进行解量化
h) 以8×8为样本单位进行IDCT变换
-JPEG still image compression
Function of the documents as follows:
1) JPEG compression process: gendat.exe
2) For the compressed JPEG file header data, together with the procedures genjpg.exe
3) The solution JEPG compression program extrdat.exe
Of which: (1) the input parameters is the need to generate the compressed file s name.
The main program flow is:
a) procedures for initialization, read the file name, the original image data and other basic data
b) From the AC.TAB and DC.TAB two file generation AC table and DC table, into an array of
c) with 8 × 8 sample units for the DCT-
d) to 8 × 8 for the sample unit to quantify
e) to 8 × 8 for the sample units of Z-scan
f) to 8 × 8 for the sample units of entropy coding
g) to 8 × 8 for the sample unit to extract the quantitative
h) with 8 × 8 for the sample units IDCT transform
