Sublinear function

Okay kiddo, let me explain what a sublinear function is.

Imagine you have a toy box with lots of toys in it. Now, let's say you have to count all the toys in the box. If you had to count one toy at a time, it could take you a really long time, especially if there are a lot of toys in the box.

But, if you were able to count multiple toys at once, it would be faster, right? For example, if you counted toys in groups of 3, you could finish counting all the toys in the box much faster than counting them one by one.

A sublinear function is kind of like counting toys in groups. It means that as the size of something (like the number of toys in the box) gets bigger and bigger, the time it takes to do something related to that size (like count all the toys) doesn't increase as fast. Instead, it increases slower than the size itself.

So, in our toy box example, a sublinear function might mean you can count all the toys in half the time it would take if you counted them one by one.

I hope that helps you understand what a sublinear function is, kiddo!
