So imagine you have a bunch of toys and you need to put them in different boxes. But you want to use as few boxes as possible.
Now, there are some boxes that are bigger than others. And the toys may also have different sizes.
So you have to figure out how to put the toys in the boxes so that you use as few boxes as possible. This is called the bin packing problem.
It's like trying to fit all your clothes in a suitcase before going on vacation. You want to use the least amount of suitcases and have everything fit nicely inside.
The bin packing problem is important in computer science because it helps us figure out how to store things on a computer efficiently. It can also be used to optimize transportation and packaging of goods.
