	}

与

//	for(i=1;i<=n;i++){
//		t[i].push_back(0);
//		for(j=1;j<=n;j+=i)
//			t[i].push_back(qiu(j,min(n,j+i-1)));	
//	}
	for(i=1;i<=n;i++){
//		g[i].push_back(0);
		add(i,1);las=0;
		for(j=1;j<=n;j+=i){
//			g[i].push_back(max(g[i][j/i],t[i][j/i+1]));	
			las=max(las,qiu(j,min(n,j+i-1)));
			b[las].push_back(i);
		}
	}

的区别在哪里
