函数bubbleSort(int arr[],int n,int(*compare)(int,int))的功能是根据调用时传递的比较，函数compare对数组arr的前n个元素进行排序。
问题内容：
设有如下数组定义：
int data1[]={4,2,6,3,1};
int data2[]={4,2,6,3,1};
int data3[]={4,2,6,3,1};
请分别给出下面的函数调用执行后，数组data1、data2和data3各自的元素序列。
（1）bubbleSort(data1,5,less);
（2）bubbleSort(data2,5,larger);
（3）bubbleSort(data3,3,larger);
正确答案及解析
正确答案
解析
（1）{1,2,3,4,6}
（2）{6,4,3,2,1}
（3）{6,4,2,3,1}
解析：在bubbleSort函数中，第二个参数表示进行比较元素的个数，第三个参数表示进行排序的方式，如果传入less函数，则是从小到大排序；如果传入larger函数，则是从大到小排序。swap函数是将两元素值进行相互交换；less函数是判断x和y的关系，如果x＜y，则函数值为真；larger函数是判断x和y的关系，如果x>y，则函数值为真。
