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

Parallel processing

The process of running two or more processors together is known as parallel processing. In parallel processing, a single process is divided into multiple parts, and each individual part is executed at the same time. It is used to handle various parts of a task at the same time. The main advantage of parallel processing is the reduction of the processing time of the program, where the processor in a system is the CPU. Hence, parallel processing can be performed by using multiple CPUs, and having more than one CPU creates a multi-processor. Another name of parallel processors is block processors. Here, the size of a block is the number of inputs that can be processed simultaneously in a single clock cycle.

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.
ea date object from the input string.
a Create
- 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/vy.
a Hint: LUse strftime to format 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
