visual force development with following scenario

I everyone, Recently I faced this interview question, can anyone help me to.............CREATE VISUALFORCE with below scenario
Q) We have a page which displays multiple records of Invoice Object, In this page we have a checkbox column with checkbox
    at each row.
    
    when we select a checkbox of any records, then delete button has to be displayed and when we click on the delete
    button, the selected records must be deleted.
    
    At the bottom of the page we have PREVIOUS and NEXT buttons, because all the 3,00,000 records we cannot display in
    a single page.

Hi Abhilash,

Greetings!

You can write the validation to display/hide the button and also implement the pagination to display the next and previous buttons to achieve the requirement.

Please mark it as best answer if it helps you to fix the issue.

Thank you!
