Subset sum problem

Imagine you have a bunch of toys and you want to put them into different bags. You want to make sure each bag has toys that add up to a certain number. So, if you want the toys in the bag to add up to 10, you would try different combinations of toys until you find a group that adds up to 10. That's called the Subset Sum Problem!

The subset sum problem is a math problem that deals with trying to find if there is a group of numbers that add up to a certain number. It can get really tricky if you have a lot of different numbers and don't know which ones to choose to make the sum work out.

People use the subset sum problem to help with things like cryptography (keeping secrets safe) and finding ways to divide resources (like how much money to give different departments in a company). It can be hard, but it's also really important!
