Binary Search Trees, or BSTs, are an interesting topic in computer science. They help us find, insert, and delete data quickly. But, just like any tool, they have their good and bad sides. It’s important to know both to make wise choices when we use them.
One big advantage of Binary Search Trees is how easily we can search through them. If a BST is balanced, it can find items in about time. This means if you have a lot of nodes (or parts) in the tree, it can cut the number of items to search in half each time you look. This is similar to how a binary search works with regular lists. So, when we have a ton of data, BSTs can find what we need way faster than simple searches.
Another great thing about BSTs is that they can change size. Unlike arrays, which need a set size when we make them, BSTs can grow or shrink whenever we need. That means we can add or take away nodes at any time without getting worried about messing up our data. This is super helpful when we constantly update our information.
We can also look through BSTs in different ways—like in-order, pre-order, and post-order. This means we can see the data in various orders based on what we need. For example, if we look at a BST in order, we can get everything sorted out, which is great if we want things in a specific sequence.
However, BSTs aren't perfect and have their problems. The biggest issue happens when the tree gets unbalanced. If we add nodes in order, like 1, 2, 3, the tree can turn into a straight line, like a linked list. When that happens, searching for items can take time, which is much slower.
Another downside is that keeping the BST balanced can make the code harder to write. There are special types of trees, like AVL trees or Red-Black trees, that balance themselves automatically. But this can make the code more complicated and easier to have mistakes.
BSTs also use more memory than arrays because each node needs to remember where its children are. This could be a problem in systems where memory matters a lot, leading to wasted space.
Lastly, how we traverse or go through a BST depends on how balanced it is. If it’s not balanced, traversing can take longer and feel more clunky, which can be a hassle with large amounts of data.

In the end, using Binary Search Trees is all about knowing the data and what the application needs. They are powerful tools for managing data, but we should keep an eye on their weaknesses, especially when working with lots of changing data.
