Redo the binary search tree class to implement lazy deletion. Note carefully that this affects all of the routines. Especially challenging are findMin and findMax, which must now be done recursively. Based on this, describe any modifications that you would need to make to the BinaryNode itself, and then show the implementation for findMin. You don't actually have to give us a full working class, only a description of the modification plus the findMin code. (In Java)
