迷官
說明
由於迷宮的設計,老鼠走迷宮的入口至出口路徑可能不只一條,如何求出所有的路徑呢?
解法
求所有路徑看起來複雜但其實更簡單,只要在老鼠走至出口時顯示經過的路徑,然後退回上一格重新選擇下一個位置繼續遞迴就可以了,比求出單一路徑還簡單,我們的程式只要作一點修改就可以了。

得分排行
說明
假設有一教師依學生座號輸入考試分數,現希望在輸入完畢後自動顯示學生分數的排行,當然學生的分數可能相同解法
這個問題基本上要解不難,只要使用額外的一個排行陣列走訪分數陣列就可以了,直接使用下面的程式片段作說明:for(i = 0; i <>
juni[i] = 1;
for(j = 0; j <>
if(score[j] > score[i])
juni[i]++;
}
}
printf("得分\t排行\n");
for(i = 0; i <>
printf("%d\t%d\n", score[i], juni[i]);
juni[i] = 1;
for(j = 0; j <>
if(score[j] > score[i])
juni[i]++;
}
}
printf("得分\t排行\n");
for(i = 0; i <>
printf("%d\t%d\n", score[i], juni[i]);
上面這個方法雖然簡單,但是反覆計算的次數是n^2,如果n值變大,那麼運算的時間就會拖長;改變juni陣列的長度為n+2,並將初始值設定為0,如下所示:
接下來走訪分數陣列,並在分數所對應的排行陣列索引元素上加1,如下所示:
將排行陣列最右邊的元素設定為1,然後依序將右邊的元素值加至左邊一個元素,最後排行陣列中的「分數+1」」就是得該分數的排行,如下所示:
這樣的方式看起來複雜,其實不過在計算某分數之前排行的人數,假設89分之前的排行人數為x人,則89分自然就是x+1了,這也是為什麼排行陣列最右邊要設定為1的原因;如果89分有y人,則88分自然就是x+y+1,整個陣列右邊元素向左加的原因正是如此。
如果分數有負分的情況,由於C/C++或Java等程式語言無法處理負的索引,所以必須加上一個偏移值,將所有的分數先往右偏移一個範圍即可,最後顯示的時候記得減回偏移值就可以了。
import java.io.*;
public class ScoreRank {
public static void main(String[] args)
throws NumberFormatException, IOException {
final int MAX = 100;
final int MIN = 0;
int[] score = new int[MAX+1];
int[] juni = new int[MAX+2];
BufferedReader reader =
new BufferedReader(
new InputStreamReader(System.in));
int count = 0;
do {
System.out.print("輸入分數,-1結束:");
score[count++] =
Integer.parseInt(reader.readLine());
} while((score[count-1] != -1));
count--;
for(int i = 0; i < count; i++)
juni[score[i]]++;
juni[MAX+1] = 1;
for(int i = MAX; i >= MIN; i--)
juni[i] = juni[i] + juni[i+1];
System.out.println("得分\t排行");
for(int i = 0; i < count; i++) {
System.out.println(score[i] + "\t" +
juni[score[i]+1]);
}

從Java應用程序存取Microsoft Excel檔案
感謝Apache,現在 利用POI,有辦法提供Java的應用程序存取Microsoft Excel文件(.xls )。 POI 可以從apache.org 下載。 以下是小教程如何寫入Excel文件。 寫Excel文件步驟是:
- 創建輸出文件使用FileOutputStream
- 創建一個新工作簿創建一個實例級 HSSFWorkbook
- 創建一個新的資產負債表,建立的一個實例級 HSSFSheet
- 創建字體對象援引法createFont ( )的類 HSSFWorkbook
- 創建細胞風格對象援引法createCellStyle ( )的類 HSSFWorkbook
- 創建數據格式對象援引法createDataFormat 階級 HSSFWorkbook
- 創建行致電方法createRow ( rowNumber )由實例HSSFSheet
- 收件簿到輸出文件。
import java.util.*;
import org.apache.poi.hssf.usermodel.*;
import java.io.*;
public class WriteSimpleXLS{
public WriteSimpleXLS() {
try{
FileOutputStream fos = new FileOutputStream("output.xls");
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet s = wb.createSheet();
HSSFRow r = null;
HSSFCell c = null;
HSSFCellStyle cs = wb.createCellStyle();
HSSFDataFormat df = wb.createDataFormat();
HSSFFont f = wb.createFont();
//set font
f.setFontHeightInPoints((short) 12);
f.setColor( (short)HSSFFont.COLOR_RED );
//set cell style
cs.setFont(f);
//set data format
cs.setDataFormat(df.getFormat(”#,##0.0〃));
wb.setSheetName(0, “First Sheet”);
//create row
r = s.createRow(0);
//create cell
c = r.createCell((short)0);
c.setCellStyle(cs);
c.setCellValue("Nico");
//create another cell
c = r.createCell((short)1);
c.setCellStyle(cs);
c.setCellValue("Ganteng");
//now that we’re done creating workbook,it’s time to write it to output file
wb.write(fos);
fos.close();
}catch(IOException e){
System.err.println(e.getMessage());
e.printStackTrace();

Ajax SmartGWT!
Today, let me introduce a framework that builds on top of GWT Google Web Toolkit, it is called SmartGWT!
SmartGWT Release Notes 1.0 b2
So what's so smart about SmartGWT?
SmartGWT is not just another Widget library. While most Ajax frameworks focus primarily on presentation and displaying mostly read-only data, either local or via XML / JSON, SmartClient was built with server side integration in mind. Most enterprise applications are not just about about data presentation, but about being able to propagate data changes made by the user to the backend. So while its tempting to use library X that has a cool tree widget, it's not until you actually try to use it your application that you encounter the real world hard problems. For example, how do you take data from your business objects on the server to not only display in a tree widget, but also be able to update your data model when, say, the user reorders the tree nodes or make edits / deletes in the UI.
Most Ajax frameworks stop short and leave it up to the user to manage state on the client side and propagating the changes to the server. This is no a trivial problem. Over the past few years UI widget libraries have improved significantly and there are now various options available to users. Simply put, having good looking widgets is not the hard problem today. In addition to having good looking widgets, having end-to-end integration of the UI components with the backend is the hard problem. It's this 20% of the functionality that takes 80% of the time in building most enterprise applications.
