write a recursive function. When the age (x) of the second person and total number (N) are input, the list of age composition of all people is output in reverse order

Try to write a recursive function

''' Suppose there are N people now, the first person is 3 years old, the second person is x years old 
(unknown), and the age of the third person is the sum of the ages of the first two people, and so 
on until the Nth person. Try to write a recursive function. When the age (x) of the second person 
and total number (N) are input, the list of age composition of all people is output in reverse order. 
Note: when the age of the M-th person is greater than 120, output ”Larger than 120!“ and the 
reverse order list of the age of the first M-1 individuals.
[example input 1]
6,4
[sample output 1]
[15, 9, 6, 3]
[example input 2]
80,9
[sample output 2]
Age 4 is larger than 120!
[83, 80, 3 '''
