经典算法-C#四种排序算法

冒泡排序

冒泡排序法
using System;

namespace BubbleSorter

{
public class BubbleSorter

{
public void Sort(int [] list)

{
int i,j,temp;

bool done=false

j
=1

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

{ done
=true

for(i=0;i<list.Length-j;i++

{

if(list[i]>list[i+1])

{

done
=false

temp
=list[i];

list[i]
=list[i+1];

list[i
+1]=temp;

} }

j
++; }

} }

public class MainClass

{
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);

forint m=0;m<iArrary.Length;m++

Console.Write(
"{0} ",iArrary

­);

Console.WriteLine();

} }

}

选择排序

选择排序
using System;
namespace SelectionSorter
{
public class SelectionSorter
{
private int min;

public void Sort(int [] list)

{
  
forint i=0;i<list.Length-1;i++
{
min
=i;

forint 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 MainClass

{
public static void Main()

{

int[] iArrary=new int[]{1,5,3,6,10,55,9,2,87,12,34,75,33,47};

SelectionSorter ss
=new SelectionSorter();

ss.Sort(iArrary);

forint m=0;m<iArrary.Length;m++

Console.Write(
"{0} ",iArrary

­);

Console.WriteLine();

}}

}

插入排序

插入排序
using System;

namespace InsertionSorter

{
public class InsertionSorter

{
public void Sort(int [] list)

{
forint i=1;i<list.Length;i++

{
int t=list[i];

int j=i;

while((j>0&&(list[j-1]>t))

{ list[j]
=list[j-1];

--j;

}

list[j]
=t; }

}

}

public class MainClass

{
public static void Main()

{

int[] iArrary=new int[]{1,13,3,6,10,55,98,2,87,12,34,75,33,47};

InsertionSorter ii
=new InsertionSorter();

ii.Sort(iArrary);

forint m=0;m<iArrary.Length;m++

Console.Write(
"{0}",iArrary

­);

Console.WriteLine();
} }

}

希尔排序

 希尔排序是将组分段,进行插入排序.

希尔排序法
using System;

namespace ShellSorter

{

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

{

forint i=inc+1;i<=list.Length;i+=inc)

{

int t=list[i-1];

int j=i;

while((j>inc)&&(list[j-inc-1]>t))

{

list[j
-1]=list[j-inc-1];

j
-=inc;

}

list[j
-1]=t;

} }

} }

public class MainClass

{
public static void Main()

{

int[] iArrary=new int[]{1,5,13,6,10,55,99,2,87,12,34,75,33,47};

ShellSorter sh
=new ShellSorter();

sh.Sort(iArrary);

forint m=0;m<iArrary.Length;m++

Console.Write(
"{0} ",iArrary

­);

Console.WriteLine();

} }

}
