11.12 LAB: Dates Complete the code to implement the following operations: 1. Complete read_date(): • Read an input string representing a date in the format yyyy-mm-dd. o Create a date object from the input string. • Retum the date object. 2. Call read_date() to read four (unique) date objects and store the date objects in a list. 3. Call sorted() to sort the list of date objects, earliest first. Store the sorted dates in a new list. 4. Output the sorted_dates, in the format mm/dd/yy. • Hint: Use strftime() to farmat the date outputs. (See resource below.) 5. Output the number of days between the last two dates in the sorted list as a positive number. 6. Output the date that is 3 weeks from the most recent date in the format 'July 4, 1776'. • Hint: Use timedelta() to set a duration of time for the arithmetic on date objects. (See resources below.) Ex: timedelta(days=50, seconds=27, hours=B, weeks=2) will define a duration of 50 days + 27 seconds + 8 hours + 2 weeks. 7. Output the full name of the day of the week of the earliest day. Ex: If the input is: 2022-01-27 2022-07-04 2020-12-31 2022-07-29 the output is: 12/31/2020 01/27/2022 07/04/2022 07/29/2022 25 August 19, 2022 Thursday

For keyboard navigation. SHOW MORE v a The idea of a map is to be able to look up one value with another. Often the lookup value is called the key and the looked-up value is called simply the value. As such, we see that any data structure essentially performs the actions required of a map.

Task 2: Login System Implement the function loginUser() that takes two String as input, one for user email and another for password. It will search for the given user email in emailArr. If the user email exists and the given password matches with the stored one against that email, then login will be successful and you should return the array index plus show a success message. Otherwise, login will be unsuccessful and you should return FAIL_VAL plus show a proper error message.
