When a node is deleted, the binary search property of the tree must be preserved, i.e. that the left subtree of the deleted node must contain only values less than the deleted node, and the right subtree must contain only values greater than the deleted node. Deletion in a binary search...

case 1: if the delete node is leaf node, then we can simply remove it case 2: if the delete node is has single side or substree case 3: it has two children, then to keep it as a valid binary search tree, we can copy the min value from right subtree to delete node, to convert...

Thetwalksubroutine steps through the binary search tree whose root is pointed to by theRootPointerparameter. (Any node in a tree can be used as the root to step through the tree below that node.) TheActionparameter is the name of a routine to be invoked at each node. The routine specif...
