Weak inverse

Okay, so imagine you have two friends named A and B. A tells you a secret code that you and B need to crack in order to open a special treasure chest. But the code is really hard and you can't figure it out on your own.

So you ask B for help. B is really good at solving codes, but even they can't solve this one on their own.

But then, B thinks of a trick. They remember something called a "weak inverse" that could help crack the code. Basically, a weak inverse is a way to flip the order of some numbers in a code to make it easier to solve.

So B uses the weak inverse trick on the code and it becomes much easier to solve. You and B work together and crack the code, opening the treasure chest and finding lots of goodies inside!

So, in summary, a weak inverse is a trick that can help you solve a really hard code by rearranging some of the numbers. It's like when you and your friend work together to open a treasure chest by using a special trick.
