(Printing Trees) Write a recursive member function outputTree to display a binary tree ob- ject on the screen. The function should output the tree row by row, with the top of the tree at the left of the screen and the bottom of the tree toward the right of the screen. Each row is output verti- cally. For example, the binary tree illustrated in Fig. 20.24 is output as follows:
Note that the rightmost leaf node appears at the top of the output in the rightmost column and the root node appears at the left of the output. Each column of output starts five spaces to the right of the previous column. Function outputTree should receive an argument totalSpaces representing the number of spaces preceding the value to be output (this variable should start at zero, so the root node is output at the left of the screen). The function uses a modified inorder traversal to output the tree—it starts at the rightmost node in the tree and works back to the left. The algorithm is as
follows:
While the pointer to the current node is not null
Recursively call outputTree with the right subtree of the current node and
totalSpaces + 5
Use a for statement to count from 1 to totalSpaces and output spaces
Output the value in the current node
Set the pointer to the current node to point to the left subtree of the current node Increment totalSpaces by 5.
