How many steps does it take to delete an item from a binary search tree (BST )? explain Deleting from a Binary Search Tree (BST)

Remove from Binary Search Tree (BST). 

A binary search tree (BST), which is more involved than either searching or inserting, can be deleted. This is one of the most difficult concepts for novice programmers. You can delete an item from BST in four steps: identify the node you want to delete; find the successor or replacement node; delete it and reconnect the tree. (Galac 2021).   Depending on what type of replacement is chosen, there may be additional steps. To get the successor, if the successor node lies on the right-hand side of the subtree then an extra step may be required. To link the parent to the replacement node if it is on the right side of the subtree, you must take an extra step (Pion 2015). If the replacement node does not contain a leaf, you will need to take an extra step and delete the appropriate sub-tree. (Galac 2021).  The steps required to remove an item from a BST can vary depending on which replacement node you choose.   References  Galac, T. (2021).
