12.ObjectsAndClasses-Students
Write a program that receives a count of students - n and orders them by grade in descending order. Each student should have a First name (string), a Last name (string) and a grade (a floating-point number).
Input
• On the first line, you are going to receive n - the count of students
• On the next n lines, you will be receiving the info about the students in the following format:
"{first name} {second name} {grade}"
Output
• Print each student in the following format: "{first name} {second name}: {grade}"
