Output should look like this:

PreOrder:

1 2 5 6 9

InOrder:

1 2 5 6 9

Postorder:

9 6 5 2 1

BreadthFirst:

1 2 5 6 9

Populate a binary search tree from an input file (input.txt) that contains a list of numbers. The file can
also contain the keyword delete followed by a number. Search for a node within the tree for that
number and delete it. If the number is not found, insert the node. The tree will not contain any
duplicates.
Sample input.txt file
1238568
delete 3
delete 9
Note:
delete 8
8
The above lines will not be in the file because delete 8 will insert a new node since it doesn't exist and
then, the 8 on the next line will attempt to insert a second 8, which would be a duplicate.
At the end, display the tree in preorder, inorder, and postOrder format. Also, display the tree level by
level (breadth search format). The display should be redirected to a file (output.txt).
Note: When deleting, make sure to account for no children, one child and two children.
