Web6 apr. 2024 · A depth first search moves from parent to child from the root all the way down a single line of subtrees, reaching the bottom-most child, the leaf node which has no children of its own. When a single vertical parent-child line can be traversed no farther, the line is backtracked until a parent node with an untraveled child node is reached.
