旋转二维数组的最快方法

def rotate_array(matrix):
    # 转置矩阵
    for i in range(len(matrix)):
        for j in range(i, len(matrix[0])):
            matrix[i][j], matrix[j][i] = matrix[j][i], matrix[i][j]
    
    # 逆序操作
    for i in range(len(matrix)):
        left, right = 0, len(matrix[0]) - 1
        while left < right:
            matrix[i][left], matrix[i][right] = matrix[i][right], matrix[i][left]
            left += 1
            right -= 1
    
    return matrix
