将代码过程比较常用的一些代码片段备份一下,如下的代码内容是关于C#使用快速排序法给一个字符串数组排序的代码。
class Quicksort {
private void quickSwap(string[] Array, int Left, int Right)
{
string Temp = Array[Right];
Array[Right] = Array[Left];
Array[Left] = Temp;
}
public void quickSort(string[] Array, int Left, int Right)
{
int LHold = Left;
int RHold = Right;
Random ObjRan = new Random();
int Pivot = ObjRan.Next(Left, Right);
quickSwap(Array, Pivot, Left);
Pivot = Left;
Left++;
while (Right >= Left)
{
int cmpLeftVal = Array[Left].CompareTo(Array[Pivot]);
int cmpRightVal = Array[Right].CompareTo(Array[Pivot]);
if ((cmpLeftVal >= 0) && (cmpRightVal < 0))
{
quickSwap(Array, Left, Right);
}
else
{
if (cmpLeftVal >= 0)
{
Right--;
}
else
{
if (cmpRightVal < 0)
{
Left++;
}
else
{
Right--;
Left++;
}
}
}
}
quickSwap(Array, Pivot, Right);
Pivot = Right;
if (Pivot > LHold)
{
quickSort(Array, LHold, Pivot);
}
if (RHold > Pivot + 1)
{
quickSort(Array, Pivot + 1, RHold);
}
}
}
