题意：
略。

思路：
一开始想DFS直接搜出来，然后打表。。然后n=15的时候跑不出来了。。。。

原来那么简单：

所以每次推一推就好了，嘤嘤嘤，大水题想了半天。

#include<iostream>#include<cstdio>#include<cmath>#include<cstring>#include<algorithm>using namespace std;int a[20][20]={{2,3,6},{2,4,6,12},{2,4,8,12,24},{3,4,6,8,12,24},{2,6,8,12,16,24,48},{3,4,6,12,15,20,30,60},{3,4,7,12,14,21,28,42,84},{3,5,6,8,20,24,30,40,60,120},{3,5,8,10,15,20,24,30,40,60,120},{4,5,8,10,12,15,20,24,30,40,60,120},{3,6,9,10,15,18,20,30,36,45,60,90,180},{4,6,9,10,12,15,18,20,30,36,45,60,90,180},{3,5,6,16,28,33,36,39,42,45,48,56,70,88,130},{3,5,6,16,33,36,39,42,44,45,48,56,70,77,88,130},{3,5,6,20,33,36,39,42,44,45,48,56,70,77,80,88,130},{3,5,6,24,33,36,39,42,44,45,48,56,70,77,80,88,120,130},};int main(){    for(int i=0,n=3;n<=18;i++,n++)    {        for(int j=0;j<n;j++)        {            if(j) printf(" ");            printf("%d",a[i][j]);        }        puts("");    }}
