杨辉三角java代码么
以下是杨辉三角的Java代码:
import java.util.Scanner;
public class YangHuiTriangle {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("请输入要打印的行数:");
int n = scanner.nextInt();
int[][] arr = new int[n][n];
for (int i = 0; i < n; i++) {
for (int j = 0; j <= i; j++) {
if (j == 0 || j == i) {
arr[i][j] = 1;
} else {
arr[i][j] = arr[i-1][j-1] + arr[i-1][j];
}
System.out.print(arr[i][j] + " ");
}
System.out.println();
}
}
}
运行之后,输入要打印的行数,例如输入5,会输出以下内容:
请输入要打印的行数:
5
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
