I am working on a project for school, and the assignment has us: Implement the Tree-Insert(T,z) operation on a binary search tree. Now 40 is less than 56, so tmp goes to left and now points to B, address of 45. Then depending on which way we go, that node has a left and a right and so on. Draw the tree after each insertion. root=InsertNode(root,8); one that has min height. To insert a value, just find where that value would have been, had it already been in the tree, then add the value as a new leaf. The in-order traversal of the resultant binary search tree is.
