how can we delete a node with two childs in binary tree??using its right sub tree

[Vuhelper]

When there are two child nodes of a node to be deleted, then there are two ways to delete it:
using its right subtree:
replace the node to be deleted with the left-most child in its right subtree.

using its left subtree:
replace the node to be deleted with the right-most child in its left subtree.
