3. We need to build a height filter for a new rollercoaster in town. The program receives HashMap where the keys are names, and the values are heights (in centimeters). Our task is to delete all entries from the HashMap where the height is less than 140, without creating a new array. I The starting HashMap is as follows: HashMap people = new HashMap(); people.put("David", 150); people.put("Tom", 180); people.put("Robert", 130); people.put("Alice", 125); people.put("Sophie", 145); people.put("Maria", 120);
