Discrete Mathematics
A leaf node is a node in a tree structure that does not have any children, meaning it is at the end of a branch. In binary trees and binary search trees, leaf nodes represent the final points where data is stored, and they play a crucial role in traversals, search operations, and overall structure efficiency. In the context of data compression, particularly with Huffman coding, leaf nodes are vital as they represent the encoded symbols with their corresponding frequencies.
