Union (computer science)
Okay, so imagine that you have some toys - a teddy bear, a doll and a toy car. Each toy is different and has its own characteristics.
Now let's say you want to put all your toys together in one box. You could just dump them in there, but then it might be hard to find a specific toy when you want to play with it.
Instead, you can group your toys based on certain qualities they share. For example, you can put all the toys that are soft (like the teddy bear and the doll) in one group, and all the toys that can move (like the car and the doll) in another group.
This is kind of like what happens when you use a data structure called a union in computer science. It allows you to group together several variables or data types that share something in common.
For example, imagine you have several lists of numbers - one list for even numbers and another list for odd numbers. Rather than keeping them separate, you can use a union in your computer program to create a new list that contains all the numbers from both lists.
Just like with the toy example, grouping similar things together makes them easier to understand and work with. In computer science, a union is a tool that helps programmers organize and manipulate data more efficiently.
