Write a Python program to manage employee records using a table data structure. The program should read employee records from an input file $($as shown in Figure $3)$ and provide the following functionalities:

$>$ A function 'display$()\text{'}$ to display employee records by a given department name: display the table of employee records from the given department, including column headers; as shown in sample output Figure $4.$

Main function: opens and reads employee records into a table. Then find the grade of the employee based on his$/$her salary and add it to the table as $4^{th}$ column, as follow:

Grade C: Salary less than $$1,000$

Employee Name; Department; Salary

Ahmed Al$-$Awfi; COMP; $3200\mathrm{.}99$

Salah Al$-$Sinani ; COMP; $2075$

Rashid Al$-$Ali ; Admin; $1931\mathrm{.}4$

Kamla Al$-$Subhi ; Admin; $815$

Hind Al$-$Wardi ; COMP; $986\mathrm{.}5$

Said Al$-$Mosa; Finance; $3130\mathrm{.}2$

Figure $3$ sample input file 'students.txt$\text{'}$

Grade B: Salary in the range $$1,000,$$$3,000$

Grade A: Salary greater than $$3,000$

Prompt user for the department name and display employee records from the given department if exist by calling the 'display$()\text{'}$ function.
