WebJun 8, 2024 · This is the most simple implementation of Depth First Search. As described in the applications it might be useful to also compute the entry and exit times and vertex color. We will color all vertices with the color 0, if we haven't visited them, with the color 1 if we visited them, and with the color 2, if we already exited the vertex. WebAug 3, 2024 · In pre-order traversal of a binary tree, we first traverse the root, then the left subtree and then finally the right subtree. We do this recursively to benefit from the fact that left and right subtrees are also trees. Traverse the root. Call preorder () on the left subtree. Call preorder () on the right subtree. 2.
