input: Write a python function to take a user's name and age as input, split the input into name and age, and print a message with the age incremented by 1.
  assert increment_age("John 10") == "Hi John, you are 11 years old"
  assert increment_age("Alice 25") == "Hi Alice, you are 26 years old"
  assert increment_age("Bob 40") == "Hi Bob, you are 41 years old"
output: def increment_age(user_input):
      name, age = user_input.split()
      age = int(age) + 1
      return f"Hi {name}, you are {age} years old"
