    1. (p-> info! = NULL);
    2. (p-> info == NULL);
    3. (p-> next! = NULL);
    4. (p-> next == NULL);
  2. Question 2. When removing node x in the search binary tree, we only need to check that:
    1. x is the left leaf node of the binary search tree or not
    2. x is the right leaf node of the binary search tree
    3. The existence of x on the tree
    4. All 3 answers above

  4. Question 4. Which of the following signs indicates a single list of empty links:
    1. (p-> right == NULL);
    2. (p-> info == NULL);
    3. (p == NULL);
    4. (p-> next == NULL);
  5. Sentence 5. Which sign indicates that the right node of p has the right subtree:
    1. (p-> right! = NULL);
    2. (p-> left! = NULL);
    3. (p-> right! = NULL) && (p-> right-> right == NULL);
    4. (p-> right! = NULL) && (p-> right-> right! = NULL);

  7. Question 7. A binary tree is called true if:
    1. The original node and all intermediate nodes have 2 child nodes
    2. The key value of the root node is always greater than the value of the keys of the right sub-branch

    3. The key value of the root node is always greater than the value of the keys of the left sub-branch
    4. Both the root node and intermediate nodes have two child nodes and the leaf nodes have the same level
  8. Question 8. When performing the operation of adding a leaf node x to the right of node p of the normal binary tree, we need:
    1. Check for the existence of p and the right leaves p;
    2. Check the existence of leaf nodes on the right p
    3. Check for the existence of node p
    4. There is no need to perform all three conditions outlined in the question
  9. Question 9. For the following program section:
     int a, * p, * q; 

     float * t;
