[问题描述] 将N个关键字去整数的记录进行整序， 以使所有关键字为非负数的记录排在关键字为负数的记录之前，要求使用最少的附加空间，且算法的时间复杂度为O（N） [输入] 待排序记录个数，各关键字的值。 [输出] 关键字从正负分开，正数在前 [存储结构] 待排序记录顺序存储。 [算法的基本思想] 快速排序算法每次任取一个记录的关键字为标准，将其余记录分为两组将，N个关键字去整数的记录进行整序， 以使所有关键字为非负数的记录排在关键字为负数的记录之前。 #include using namespace std #define MAXNUM 100//设文件的最长可能长度 void sort(int* keys, const int len)//排序 -[Problem Description] N keyword to the integer sequence the entire record. keyword so that all non-negative Records with the keyword for the negative record, at least require the use of the additional space and time complexity of the algorithm is O (N) [imported] to be sort record number, The value of the keyword. [Output] keyword separate from the pluses and minuses are several former [storage structure] scheduling records to be stored sequence. [Algorithm for the basic idea] quick sort algorithm each time a record for any keyword as a standard, The remaining records will be divided into two groups, N-keyword
