Multiple subset sum problem

Okay kiddo, imagine you have a bunch of toys in a box. Each toy has a number on it, and you also have a calculator. Now, let’s say your mom tells you to find two subsets of toys that have the same sum of their numbers.

What does that mean? It means you need to pick some toys from the box and add the numbers on them, then pick some more toys (maybe the same number of toys, maybe not) and also add their numbers, and make sure that both of those sums are the same.

But wait, there’s more! Your mom actually wants you to find ALL the possible pairs of subsets that have the same sum.

So you start picking toys and adding their numbers, then pick more toys and add their numbers, and keep doing that until you’ve found all the pairs of subsets with equal sums. It might take a while, but you can use the calculator to help you add the numbers up faster.

This is called the multiple subset sum problem, and it’s like a big puzzle that sometimes people need to solve in math, computer science, or other fields.
