It sounds like you are looking for a network. If a node can not find a network to connect to, then it cannot connect.
Solution:
Since no language was specified, this will be written in Python.
n1, n2, n3 = input ("Enter three names: ").split()
print(n3)
print(n2)
print(n1)

You're setting the value of user_num to 20. Doing this won't allow the other test cases to run. Simply delete that line and your code should work. This is the code I wrote:
user_num = int(input())
while user_num>=1:
user_num/=2
print(user_num)
I wrote my code in python 3.8. I hope this helps.
