A tree is a type of data structure that is hierarchically organized with elements that have specific relationships. Understanding trees, one of the commonly used data structures, and implementing basic traversal algorithms is very useful in coding tests. In this article, we will start with the basic concepts &hellip; \ub354 \ubcf4\uae30 \"\""}
