A passive data structure is like a container that you can use to keep things organized. Imagine you have a box where you can put your toys. Each toy has a different shape and size, like a ball, a teddy bear, or a puzzle. Instead of throwing them all around the room, you can put them inside the box.
Now, let's think about passive data structures in computer programming. Instead of toys, we have different types of information, like numbers, words, or even more complex things. These pieces of information are called data. And just like with toys, we want to keep them organized.
A passive data structure is like a special box in a computer that can hold different types of data. It has some rules on how things are stored and how we can access them.
One example of a passive data structure is an array. It's like a row of boxes, and each box can hold a different piece of information. For example, you can have an array to store the numbers 1, 2, 3, and 4. They will be stored in sequential order, so the first box holds 1, the second box holds 2, and so on. This makes it easy for the computer to find and retrieve the data we want.
Another example is a linked list. It's like a chain of boxes, where each box has a reference to the next box in line. This allows us to add or remove boxes easily, like adding or removing links in a chain.
Passive data structures are called passive because they don't change or modify the data by themselves. They just hold the information and give us ways to access and manipulate it.
So, in simple terms, a passive data structure is like a special box or chain that holds and organizes different kinds of information in a computer. It makes it easier for us to find and use the data when we need it.
