发帖数: 7 | 3 我想到一个方法，各位大牛帮忙看下啊
扫描一遍数组 得到最小值min，令它的hashcode为 2，
再扫描一遍数组， 令a[i]的hashcode就是第(a[i]-min)个prime number 求积得出数组
的hashcode，比较两个数组的hashcode即可
我现在采用的做法是用primearray存了10000以内的prime number， 也可以用数学的方
法算（但这样的时间复杂度是n2？）。
public class ArrayEquality {
static boolean arrayequality(int a[], int b[])
{
int max=a[0];
int min=a[0];
long a_hashcode = 1;
long b_hashcode = 1;
int primearray[] ={2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61
