A. Little Pony and Crystal Mine

Twilight Sparkle once got a crystal from the Crystal Mine. A crystal of size n (n is odd; n > 1) is an n × n matrix with a diamond inscribed into it.

You are given an odd integer n. You need to draw a crystal of size n. The diamond cells of the matrix should be represented by character "D". All other cells of the matrix should be represented by character "*". Look at the examples to understand what you need to draw.

Input

The only line contains an integer n (3 ≤ n ≤ 101; n is odd).

Output

Output a crystal of size n.

画图题,就是画一个像菱形一样的东西。具体看代码吧,比较好懂。

 1 #include<iostream>
 2 using namespace std;
 3 int n;
 4 int main(){
 5     cin >> n;
 6     int t=0;
 7     for (int i=1;i<=n/2;++i) {
 8         int t=n/2-i+1;
 9         for (int j=1;j<=t;++j) cout <<"*";
10         for (int j=1;j<=n-t*2;++j) cout <<"D";
11         for (int j=1;j<=t;++j) cout <<"*";
12         cout << endl;
13     }
14     for (int i=1;i<=n;++i) cout <<"D";
15     cout <<endl;
16     for (int i=1;i<=n/2;++i) {
17         for (int j=1;j<=i;++j) cout <<"*";
18         for (int j=1;j<=n-i*2;++j) cout <<"D";
19         for (int j=1;j<=i;++j) cout <<"*";
20         cout << endl;
21     }
22     return 0;
23     }
