Description
在一本算法结构的书中,介绍的快速排序,每一趟排序都会去交换。
但这里的好像只是找到了比基准值大的和小的两个数组,然后最后再去合并。
书上的c的实现:
`int Quick(List R, int low, int high)
{
x=R[low];
while(low<high)
{
while((low<high) && R[high].key >= x.key)
{
high --;
}
R[low] = R[high];
while(low<high && R[low].key <= x.key)
{
low++;
}
R[high] = R[low];
}
R[low] = x;
return low;
}
void QuickSort(List R, int low, int high)
{
if (low < high)
{
temp = Quick(R, low, high);
QuickSort(R, low, temp - 1);
QuickSort(R, temp + 1, high);
}
}`
