You are organizing a group trip and need to transport everyone using a fleet of available cars. You are given the total number of people who need to travel and a list of the seating capacities of the cars you have.

Your task is to determine the minimum number of cars required to transport all the people.

You are given a string s containing words separated by spaces. Your task is to find and return the first word in the string that satisfies two conditions:

1) The word must have an even length.

2) The word's length must be the maximum among all other even-length words in the string.

If multiple words of the same maximum even length exist, you must return the one that appears first in the original string.

There is a closed room with three light bulbs inside.

• You have a closed room containing three light bulbs.
• Outside the room, there are three switches, each connected to exactly one bulb (but you don’t know the mapping).
• You can toggle the switches (on/off) in any way before entering the room.
• You may open the door and enter the room only once.
• Once inside, you cannot touch the switches again — you can only observe the bulbs.

How can you determine which switch controls which bulb in a single visit?

The following is a description of the instance of this famous puzzle involving 2 eggs and a building with 100 floors.
