A tree is implemented using a node structure defined as:
struct node{
int data;
struct node *left;
strict node *right;
};
Write a function whose prototype is:
int smallest(struct node *);
which accepts a tree (pointer to the root) and returns the smallest node in the right sub-tree of the
root. If root is NULL, or if there is no right sub-tree, returm the number -999.

C++The List class represents a linked list of dynamically allocated elements. The list has only one member variable head which is a pointer that leads to the first element. See the following code for the copy constructor to List. List (const List & list) { for (int i = 0; i <list.size (); i ++) { push_back (list [i]); } } What problems does the copy constructor have? Select one or more options: 1. List (const List & list) {} does not define a copy constructor. 2. The list parameter should not be constant. 3. The new elements will be added to the wrong list. 4. Copy becomes shallow rather than deep. 5. The copy will create dangling pointers. 6. Copying will create memory leaks. 7. The condition must be: i <size () 8. head is never initialized.

Language/Type: C++ binary trees pointers recursion Write a function named hasPath that interacts with a tree of BinaryTreeNode structures representing an unordered binary tree. The function accepts three parameters: a pointer to the root of the tree, and two integers start and end, and returns true if a path can be found in the tree from start down to end. In other words, both start and end must be element data values that are found in the tree, and end must be below start, in one of start's subtrees; otherwise the function returns false. If start and end are the same, you are simply checking whether a single node exists in the tree with that data value. If the tree is empty, your function should return false. For example, suppose a BinaryTreeNode pointer named tree points to the root of a tree storing the following elements. The table below shows the results of several various calls to your function: 67 88 52 1 21 16 99 45 Call Result Reason hasPath(tree, 67, 99) true path exists…
