大佬们帮帮忙，看一下这个问题怎么解。。是一个纯粹的逻辑问题

Question

public class Test{

    /**
     * 现在程序中有一组医生排班数据，每条数据为某个医生的某天的某个时间的排班。
     * 要求对这组数据进行数据转换和处理，转换成排班表格，表格通过控制台输出即可。
     * 要求表头按照时间排序。如果某天没有排班，则表格不展示该列。某天某时间无数据则显示无排班。
     * 上午下午晚上通过Vo中的seqNo排序。
     * eg:
     * 2020-05-31 2020-06-01    2020-06-02 2020-06-04
     * 上午     李四       赵六       张三         无排班
     * 下午     赵六       张三       赵六         张三
     * 晚上     孙七          张三       无排班        张三
     * 需要注意的是，最终完成代码的代码质量（逻辑是否清晰，变量/方法命名是否合理等），将作为考察标准的一部分
