排序实现:
//选择排序算法
public class SelectionSorter
{
private int min;
public void Sort(int[] list)
{
for (int i = 0; i < list.Length - 1; i++)
{
min = i;
for (int j = i + 1; j < list.Length; j++)
{
if (list[j] < list[min])
min = j;
}
int t = list[min];
list[min] = list[i];
list[i] = t;
}
}
}
public class SelectionSorter
{
private int min;
public void Sort(int[] list)
{
for (int i = 0; i < list.Length - 1; i++)

list[min] = list[i];
list[i] = t;
}
}
}
public class BubbleSorter
{
//冒泡排序算法

{
//冒泡排序算法

{

while ((j < list.Length) && (!done))
{

j++;
}
}
}
//希尔排序
public class ShellSorter
{
public void Sort(int[] list)
{

for (inc = 1; inc <= list.Length / 9; inc = 3 * inc + 1) ;

}
list[j - 1] = t;
}
}
}
}
public class ShellSorter
{
public void Sort(int[] list)
{
int inc;
for (inc = 1; inc <= list.Length / 9; inc = 3 * inc + 1) ;
for (; inc > 0; inc /= 3)
{

list[j - 1] = t;
}
}
}
}
//插入排序
public class InsertionSorter
{
public void Sort(int[] list)
{
for (int i = 1; i < list.Length; i++)
{
int t = list[i];
int j = i;

}
}

for (int i = 1; i < list.Length; i++)
{
int t = list[i];
int j = i;

}
}
}
public class MainClass
{
//测试
public static void Main()
{
int[] iArrary = new int[] { 1, 5, 13, 6, 10, 55, 99, 2, 87, 12, 34, 75, 33, 47 };

//sh.Sort(iArrary);
for (int m = 0; m < iArrary.Length; m++)
Console.Write("{0} ", iArrary[m]);
Console.WriteLine();
}
}
后记:{
//测试
public static void Main()
{
int[] iArrary = new int[] { 1, 5, 13, 6, 10, 55, 99, 2, 87, 12, 34, 75, 33, 47 };
//BubbleSorter sh = new BubbleSorter();
//sh.Sort(iArrary);
//ShellSorter sh = new ShellSorter();
//sh.Sort(iArrary);
InsertionSorter sh = new InsertionSorter();
sh.Sort(iArrary);
//SelectionSorter sh = new SelectionSorter();
//sh.Sort(iArrary);
for (int m = 0; m < iArrary.Length; m++)
Console.Write("{0} ", iArrary[m]);
Console.WriteLine();
}
}
冒泡是不断的把小的数向前移
选择是每次取最小的,然后向已经排好的部分最后添加
插入是把下一个数插入到已经排好的序列中的合适位置
