$($a$).$ Consider that you are working as Data Analyst in an organization. The HR department needs you to carry out following operation on existing list of $10$ employees name $($you can assume $10$ names in a list here$).$

Split the list into two sub$-$list namely subList$1$ and subList$2,$ each containing $5$ names.

A new employee $($assume the name $$Kriti Brown$)$ joins, and you must add that name in subList$2.$

Remove the second employee's name from subList$1.$

Merge both the lists.

Assume there is another list salaryList that stores salary of these employees. Give a rise of $4\%$ to every employee and update the salaryList.

Sort the SalaryList and show top $3$ salaries.

Write the Python code and output for the same.

$($b$).$ Design a program such that it converts a sentence into wordlist. Reverse the wordlist then. Write the code and output for the same. Note: The code and its output must be explained technically. The explanation can be provided before or after the code, or in the form of comments within the code.
