19. Challenge cities with rain

19.1 Challenge - find cities with more rain

Below is the data of US cities and how days it rained in 2018.

data = {
  "Houston" => 104,
  "Atlanta" => 113,
  "Austin" => 88,
  "Baltimore" => 116,
  "Boston" => 126,
  "Dallas" => 81
}

We need to write a program to find names of all cities in where it rained more than 100 days.
