下面的程序可以从0....n-1中随机等概率的输出m个不重复的数。这里我们假设n远大于m
knuth(int n, int m)
{
srand((unsigned int)time(0));
for (int i = 0; i < n; i++) {
if ( ) {
printf("%d\n", i);
( );
}
}
}
A. rand()%(n-i) <= m m--
B. rand()%(n-i) < m m--
C. rand()%(n-i) >= m m++
D. rand()%(n-i) > m m++
The road of your choice, you have to go on !
