Delete the leaf node in BST

#1

I am trying to dry me wrong please correct me

#2

instead delete operator if we assign root== NULL or assign another address is not going to impact anything Right?? So what approach i should follow?

#3

https://ide.codingblocks.com/s/263675 this ways

#4

this is not correct as node is not acturally deleted
this is known as memory leakage

correct way

if(root->left == NULL && root->right == NULL) {
			delete root;
			return NULL;
		}
