冒泡排序的算法分析与改进

交换排序的基本思想是：两两比较待排序记录的关键字，发现两个记录的次序相反时即进行交换，直到没有反序的记录为止。-Bubble sort algorithm analysis and the basic idea is to improve the exchange of sort: pairwise comparison of key records to be sorted, found the opposite order of the two records that is to be exchanged, until there are no records in reverse order so far.
