js实现平面魔方

class MagicSquare {
  constructor(size = 3) {
    this.size = size;
    this.grid = this.initializeGrid();
  }

  initializeGrid() {
    const colors = ['red', 'green', 'blue'];
    const grid = [];
    for (let i = 0; i < this.size; i++) {
      const row = [];
      for (let j = 0; j < this.size; j++) {
        row.push(colors[(i + j) % colors.length]);
      }
      grid.push(row);
    }
    return grid;
  }

  rotateRow(rowIndex) {
    this.grid[rowIndex] = this.grid[rowIndex].reverse();
  }

  rotateColumn(colIndex) {
    const column = [];
    for (let i = 0; i < this.size; i++) {
      column.push(this.grid[i][colIndex]);
    }
    column.reverse();
    for (let i = 0; i < this.size; i++) {
      this.grid[i][colIndex] = column[i];
    }
  }

  printGrid() {
    console.log(this.grid.map(row => row.join(' ')).join('\n'));
  }
}

// 使用示例
const magicSquare = new MagicSquare();
magicSquare.printGrid(); // 打印初始状态
magicSquare.rotateRow(1); // 旋转第二行
magicSquare.printGrid(); // 打印旋转后的状态
magicSquare.rotateColumn(0); // 旋转第一列
magicSquare.printGrid(); // 打印再次旋转后的状态
