冒泡排序(bubblesort)
伪码:
BUBBLESORT(A)
for i ← 1 to length[A]
do for j ← length[A] downto i + 1
do if A[j] < A[j - 1]
then exchange A[j] ↔ A[j - 1]
Java 实现
public void bubbleSort(int[] a)
{
int len = a.length;
for (int i = 0; i < len; i++)
{
for (int j = len - 1; j > i; j--)
{
if (a[j] < a[j - 1])
{
int tmp = a[j];
a[j] = a[j - 1];
a[j - 1] = tmp;
}
}
}
