Electronic Memorandum

1. Basic functions of the system
Use an electronic memorandum to record future to-do matters within a certain period of time. Query and add are allowed.
2 Requirements
(1) You can set the storage method of the memo information to ensure flexible operations. A memo can contain a maximum of 100 Chinese characters. The time settings of the memo information can be precise to a specific date, a time period in a specific date, or a specific time in a specific date. You can set the recurrence of the event, such as taking the salary on the 10 th day of each month and taking the examination at AM on April 9, June 16-28.
(2) If there is an arrangement during the period when you add the service, a message is displayed.
(3) When querying, if there is a memo on the current date, it will be automatically reminded.
(4) According to the start date and end date entered by the keyboard, collect all the memo information in the period and output the result (including the time and memo information ); statistics are sorted by time.

It's so ugly.
