using namespace std;

int main(){
    int n, k, m, a[2000];
    scanf("%d",&m);
    while (m--){
        scanf("%d%d",&n,&k);

        for (int i=0;i<n;++i)
            scanf("%d",a+i);
        while (k--) next_permutation(a,a+n);
        for (int i=0;i<n;++i)
            printf("%d%c",a[i],i==n-1?'\n':' ');
    }
    return 0;
}

printf("%d%c",a[i],i==n-1?'\n':' ');
跟
cout << a[i] << (i==n-1?'\n':' ');

• c++用printf，G++用cout,这是我用自己程序的测试结果 (338) wb_jerry 2009-08-11 10:36:12
