3.3. Exercise: Leslie’s Parks

Leslie Knope is the deputy director of the department of Parks and Recreation. She wants to build a park in front of all of her friends’ houses. She loves her friends so much, but she also loves being a servant to the citizens and values their opinions. Being the reasonable thing to do, she holds a public forum to take a vote for each park to be built or not. For each park, if the votes in favor are double or more than the votes against, that park is decided to be built. Can you help Tom, Leslie’s lazy co-worker who is in charge of doing the calculation, so that he can decide if a park is going to be built or not?

Write a function named to_be_built that takes two integers as the votes in favor and against the park and returns a string either "YES" if the park is going to be built, or "NO" if not.

Sample I/O:

>>> to_be_built(12, 36)
'NO'

>>> to_be_built(27, 13)
'YES'
