Fair item allocation

Imagine you and your friend have 10 candies to share. You both want to make sure each of you gets a fair share of the candies. This means that neither of you should end up with fewer candies than the other, and both of you should be happy with what you got.

To allocate the candies fairly, you can start by taking turns picking one candy at a time until all the candies have been chosen. This method is called "rotating priorities." By taking turns, both you and your friend have an equal chance of getting the best candies.

Another method is to use the "divide and choose" algorithm. This is where one person splits the candies into two groups, and the other person gets to choose which group they want. This ensures that both parties have an equal say in how the candies are divided.

Overall, the goal of fair item allocation is to make sure that everyone involved in the allocation process is happy with what they receive. This can be achieved by using different techniques to distribute items equally and fairly.
