Exercise 4 – BST Sort
(2 marks)
For this exercise, you are to implement BST sort and test it for correctness.
As usual, your program will prompt for the name of an input file and the read and process the data
contained in this file.
The file contains a sequence of integer values. Read them and construct a binary search tree from
the values in the order they are read. Thus; the first number read will be the root of the tree.
For this exercise, you may use dynamic data, but it is better to store the numbers sequentially in an
array.
You do not need to balance the tree as you construct it.
When you have read the last value into the BST, conduct an in‐order traversal to output the values in
ascending order.
Print them 10 to a line in a 5‐character wide field.
Note: there may be duplicated value in the input file – in this case each copy of the number should
be kept in the tree and output. E.g. if the input was 3 5 3, the output would be 3 3 5.
As usual, do not use classes or STL.
Submit ex4.ext via moodle as usual where ext is one of c, cpp, java or py.
