构造随机数列

#include <iostream> #include <ctime>
using namespace std;
void sum(unsigned n,unsigned m)//构造和为n，长度为m的数列
{
    if(m==0||n<=0)
    {
        cout<<n<<endl;
        return;
    }
    unsigned t=(rand()%((unsigned)(n/m)));
    t=(t&1)?(t-1):t;
    if(!t) t+=2;
    cout<<t<<"/t";
    sum(n-t,m-1);
}
int main(void)
{
    int n=1100,k=60;
    srand((unsigned)(time(0)));
    sum(n,k-1);
    system("pause");
    return 0;
}
