scala打印倒着的九九乘法表

下面是用 Scala 打印倒着的九九乘法表的代码：

for (i <- 9 to 1 by -1) {
  for (j <- i to 1 by -1) {
    print(s"$i * $j = ${i * j}\t")
  }
  println()
}

输出结果如下：

9 * 9 = 81	9 * 8 = 72	9 * 7 = 63	9 * 6 = 54	9 * 5 = 45	9 * 4 = 36	9 * 3 = 27	9 * 2 = 18	9 * 1 = 9	
8 * 8 = 64	8 * 7 = 56	8 * 6 = 48	8 * 5 = 40	8 * 4 = 32	8 * 3 = 24	8 * 2 = 16	8 * 1 = 8	
7 * 7 = 49	7 * 6 = 42	7 * 5 = 35	7 * 4 = 28	7 * 3 = 21	7 * 2 = 14	7 * 1 = 7	
6 * 6 = 36	6 * 5 = 30	6 * 4 = 24	6 * 3 = 18	6 * 2 = 12	6 * 1 = 6	
5 * 5 = 25	5 * 4 = 20	5 * 3 = 15	5 * 2 = 10	5 * 1 = 5	
4 * 4 = 16	4 * 3 = 12	4 * 2 = 8	4 * 1 = 4	
3 * 3 = 9	3 * 2 = 6	3 * 1 = 3	
2 * 2 = 4	2 * 1 = 2	
1 * 1 = 1

帮我用scala写一个九九乘法表

好的，以下是Scala语言实现九九乘法表的代码：

object MultiplicationTable {
  def main(args: Array[String]): Unit = {
    for (i <- 1 to 9) {
      for (j <- 1 to i) {
        print(j + " × " + i + " = " + i*j + "\t")
      }
      println()
    }
  }
}

运行结果如下：

1 × 1 = 1	
1 × 2 = 2	2 × 2 = 4	
1 × 3 = 3	2 × 3 = 6	3 × 3 = 9	
1 × 4 = 4	2 × 4 = 8	3 × 4 = 12	4 × 4 = 16	
1 × 5 = 5	2 × 5 = 10	3 × 5 = 15	4 × 5 = 20	5 × 5 = 25	
1 × 6 = 6	2 × 6 = 12	3 × 6 = 18	4 × 6 = 24	5 × 6 = 30	6 × 6 = 36	
1 × 7 = 7	2 × 7 = 14	3 × 7 = 21	4 × 7 = 28	5 × 7 = 35	6 × 7 = 42	7 × 7 = 49	
1 × 8 = 8	2 × 8 = 16	3 × 8 = 24	4 × 8 = 32	5 × 8 = 40	6 × 8 = 48	7 × 8 = 56	8 × 8 = 64	
1 × 9 = 9	2 × 9 = 18	3 × 9 = 27	4 × 9 = 36	5 × 9 = 45	6 × 9 = 54	7 × 9 = 63	8 × 9 = 72	9 × 9 = 81
