WebOct 29, 2024 · Here’s an example of a binary search tree. Source: [Self] A binary search tree is a specific kind of tree with two major characteristics. Each node has at most TWO children — a left child and a right child. (This is why it’s called “binary.”) The left child (and all of its children) must be less than or equal to the parent.
