二分一行最大容量,如果check小于等于总行数就扩大,反之则缩小

查看代码
#include <bits/stdc++.h>
#define int long long
using namespace std;
int n,m;
int a[1000000],b[1000000];
bool check(int x)
{
    int now=a[1],ans=1;
    for(int i=2;i<=n;i++)
    {
        if(now+1+a[i]>x)ans++,now=a[i];
        else now+=a[i]+1;
    }
    return ans<=m;
}
signed main()
{
     cin>>n>>m;
     int left=0,right=1e15;
     for(int i=1;i<=n;i++)
     {
         cin>>a[i];
         left=max(left,a[i]);
     }
     int p=0;
     while(left<=right)
     {
         int mid=left+right>>1;
         if(check(mid))right=mid-1,p=mid;
         else left=mid+1;
     }
     cout<<p<<endl;
     return 0;
}

确定‘.’的位置并修改,按题意输出即可

查看代码
 #include<bits/stdc++.h>
using namespace std;
char ans[1000][1000];
signed main(){
	int n;
	cin>>n;
	if(n==0)cout<<"#";
	else {
		int m=pow(3,n);
		
		for(int i=1;i<=m;i++){
			for(int j=1;j<=m;j++){
				ans[i][j]='#';
			}
		}
	
		for(int i=1;i<=n;i++){
			int h=pow(3,i-1);
			int endj=h+h;
			int u=pow(3,i);
			for(int o=0;o<m/u;o++){
				for(int j=h+1+u*o;j<=endj+u*o;j++){
					for(int r=0;r<m/u;r++){
						for(int k=h+1+u*r;k<=endj+u*r;k++){
							ans[j][k]='.';
						}
					}
				
				}
				
			}
			
			
		
		}
	for(int i=1;i<=m;i++){
		for(int j=1;j<=m;j++){
			cout<<ans[i][j];
		}
		cout<<endl;
	}
	}
	
	return 0;
}
