Build your intuition. Could you figure out the right sequence for this list?

Arrange the following instructions into the correct order to merge two binary trees recursively:

Press the below buttons in the order in which they should occur. Click on them again to un-select.

Options:

  • If there exists a node:
  • Use pre-order traversal on the first tree
  • Return the root of the updated first tree
  • Continue this process for left subtrees
  • Check to see if both the tree nodes are null (there exists no node in either tree)
  • If there exists one node, update the first tree with the value of that node
  • Continue this process for right subtrees
  • If there exists two nodes, update the first tree with the sum of the values of both nodes
