# 菱形

## 题目 [菱形](https://www.acwing.com/problem/content/729/)

![[image-350e185e.png]]

## 思路分析

abs(sx - i) + abs(sy - j) <= n / 2

## 代码实现

```java
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        int cx = n / 2, cy = n / 2;
        for (int i = 0; i < n; i ++ ) {
            for (int j = 0; j < n; j ++ ) {
                if (Math.abs(i - cx) + Math.abs(j - cy) <= n / 2)
                    System.out.printf("*");
                else
                    System.out.printf(" ");
            }
            System.out.println();
        }
    }
}
```
