Which of the following is correct? a. A general tree can have a node with 3 children, but not a binary tree. O b. All of the other answers O c. A general tree can be in a form of linear, but not a binary tree. O d. A general tree can have more than 2 level, but not a binary tree.

Which of the following is wrong? a. None of the other answers b. In-order traversal of binary tree sorts all the nodes in their logical order. c. Post-order traversal of binary tree visits the node itself last. d. Pre-order traversal of binary tree visits the node itself first.

Java, please and thank you.

In a binary search tree the node with the largest value is found: O a. as the leftmost node of the tree. O b. as the rightmost node of the tree. O c. as the leftmost node of the right subtree of the root. O d. None of these are correct O e. as the root of the tree.
