您好我正在尝试在Java中实现Quicksort方法,但出于某种原因,当我只做5个元素时,我收到了堆栈溢出错误!什么想法可能是错的? 我的代码的一部分:
class QuickSort implements AbstractSort {
public int partition(int[] numbers, int start, int end)
{
int pivot = numbers[end];
int theIndex = start;
int temp;
for(int i = start; i <= end - 1; i++)
{
if(numbers[i] <= pivot)
{
temp = numbers[theIndex];
numbers[theIndex] = numbers[i];
numbers[i] = temp;
theIndex++;
}
}
temp = numbers[theIndex];
numbers[theIndex] = pivot;
numbers[end] = temp;
return theIndex;
}
public void mySort(int[] numbers, int start, int end)
{
if(start < end)
{
int myIndex = partition(numbers, start, end);
mySort(numbers, 0, myIndex-1);
mySort(numbers, myIndex + 1, numbers.length - 1);
}
else
{
return;
}
}
public void sort(int[] numbers)
{
mySort(numbers, 0, numbers.length - 1);
}
}
答案 0 :(得分:1)
问题出在mySort(numbers, 0, myIndex-1);
我应该将start设置为0而不是0,所以正确的代码看起来像这样mySort(numbers, start, myIndex-1);
