Assignment (1) final part.

1) Write a ruby function payslip_monthly to compute a monthly payslip of an individual based on his/her annual salary with 2 decimal places with unit tests.

for example: When we give an argument of "tomy" with "60000"

payslip_monthly "tomy" 60000

Then it will return an output in console:

Monthly Payslip for: "tomy"

Gross Monthly Income: $5000.00

Monthly Income Tax: $500.00

Net Monthly Income: $4500.00

As follows is Tax Bracket:

Salary Bracket	Rate
first 0 - 20000	0%
next 20001-40000	10%
next 40001-80000	20%
next 80001-180000	30%
180001 and above	40%

2) Create a POST REST API request to expose payslip_monthly. Request parameters should include employee_name and annual_salary. The response body should return JSON format. Add unit tests where you think its relevant.

{ "employee_name": string, "gross_monthly_income": string, "monthly_income_tax": string, "net_monthly_income": string, }

3) When compute monthly salary POST API is invoked, Then write the following information in a database of your choice, can use any local or cloud database

• Timestamp
• Employee Name
• Annual Salary
• Monthly Income Tax

4) Create a GET API to list out all information from Requirement 3 on JSON Format:

• unit tests where you think its relevant

{ salary_computations: [ { "time_stamp": string, "employee_name": string "annual_salary": string "monthly_income_tax": string } ] }

5) Create Feature related to the APIs

• Build a Simple UI Form to enter transactions
• Generate a CSV

Prefer use unit test framework: Rspec and Minitest

* Please provide with your answer explanation algorithm that used for payslip computation, design pattern used, unit tests wrote, post/ get api / postman, database used and if you used any extra requirement you invented.
