#include <iostream>
using namespace std;
int main()
{  
    // 上半三角
    for (int i = 1; i <= 7; i++){
        if(i%2==1){
            // 空格
            for (int j = 1; j <= 7 - i; j++){
                cout << " ";
            }
            for (int k = 1; k <= i; k++){
                cout << "* ";
            }
            cout << endl;
        }        
    }
    // 下半三角
    for (int i = 1; i <= 7; i++){
        if(i%2==1){
            for (int j = 1; j <= i+1; j++){
                cout << " ";
            }
            for (int k = 1; k <= 7 - i-1; k++){
                cout << "* ";
            }
            cout << endl;      
        }
