假设有N条数据,则暂且标记第0个数据为MIN(最小),使用OUT标记最左边未排序的数据,然后使用IN标记第1个数据,依次与MIN进行比较,如果比MIN小,则将该数据标记为MIN,当第一轮比较完后,最终的MIN与OUT标记数据交换,依次类推; 选择排序的java代码: Public void selectSort(){ Int in,out,min; for(out=0;out<nE...
sort key:排序关键字,对象集合中每个成员内的一个特殊值,根据这个值完成排序操作。 sorting:排序,按定义好的次序排列一组值的过程。参见bubble sort(起泡排序),heap sort(堆排序),insertion sort(插入排序),merge sort(归并排序),radix sort(基数排序),selection sort(选择排序),以及quick sort(快速排序)。 spanni...

Your code has one arrayarrwhich gets sorted. Yourmergemethod is supposed to be sorting parts of this array, but every time it is called it has the same whole array object. There are no sub-arrays; it's just up to this method to sort the relevant part of this one array. If this me...
