本文介绍了C#的四种排序算法:冒泡排序、选择排序、插入排序和希尔排序

 冒泡排序

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);

for(int m=0;m<iArrary.Length;m++)

Console.Write("{0} ",iArrary[m]);

Console.WriteLine();

} }


 

 

选择排序

using System;


namespace SelectionSorter

{ 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 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);

for(int m=0;m<iArrary.Length;m++)

Console.Write("{0} ",iArrary[m]);

Console.WriteLine();

} }

}
 

 

插入排序

using System;

namespace InsertionSorter

{ public class InsertionSorter

{ public void Sort(int [] list)

{ for(int 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);

for(int m=0;m<iArrary.Length;m++)

Console.Write("{0}",iArrary[m]);

Console.WriteLine();

} }

}
 

 

希尔排序

 希尔排序是将组分段,进行插入排序.

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)

{

for(int 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);

for(int m=0;m<iArrary.Length;m++)

Console.Write("{0} ",iArrary[m]);

Console.WriteLine();

} }

}
