A t-tree is a type of data structure, which is like an organizer for storing and sorting information. Think of it like an upside-down tree with lots of drawers and boxes. Every branch of the tree has a certain kind of information in it.
When you look at the t-tree, it looks like a letter 'T.' All the branches of the t-tree have a different kind of information. The top branch has a special kind of information called the 'root.' The two branches on either side of the root are called the 'left' and 'right' branches. Each branch of the tree can have information on it, like people's names, places, or numbers.
When you want to find something in the t-tree, you start at the root and 'search' through the left and right branches. You might look at the branch on the left to find a person's name and then go to the branch on the right to find where they live. Once you find the information you were looking for you can stop.
T-trees are helpful because they can store and organize lots of different types of information in one place. They make it easy to find things quickly so you can save time!
