Trees - Part 1

The video introduces nonlinear data structures, focusing on trees and their hierarchical nature. It explains key tree concepts such as nodes, roots, parents, children, and siblings, and discusses levels and edges. Real-life applications like Facebook comments, DOM structures, and chess strategies are explored. The video concludes with an exercise to reinforce understanding of tree components.
