modify it based on the Instructions below: -clicking a to add the amount (which shouldn't be displayed before pressing a, it should just have the info), -clicking b which will modify only the last name to uppercase (the first and last name are already uppercase before I press b which shouldn't be happening, and 'b' is used for another feature not just changing it to uppercase) maybe use an if statement and ask the user if they want to change it to uppercase for the first or last name, or -increase the hourly rate by 10 for comp sci majors, but keep the adding 1000 for comp sci and cyber security majors (2000 for both) -clicking b should also add 10 to the hourly rate for computer science majors when updating data so if you could implement that, please -the last thing is when clicking c, you should be able to insert a new node to the sequence with the amount calculated and display it, make it so the user can enter In the new node and have it displayed. Ask the user how many they want to input, then make a loop to have them insert the new nodes and user input. please do it in a timely manner
