BugFind the bug and fix the code

What it should do

greet_student(name) makes a Student and returns their greeting. Example: greet_student("Asha") → "Hi, Asha".

What happens instead

greet_student("Asha") crashes: AttributeError: 'Student' object has no attribute 'name'.

class Student:
    def __init__(self, name):
        name = name

    def greeting(self):
        return "Hi, " + self.name


def greet_student(name):
    return Student(name).greeting()

Test a custom input to verify an edge case (e.g. empty lists, negative numbers, duplicates).
