Plz answer to this

#1

In case 3,after replacing root data with “replace data” cant we now just delete replace instead of traversing root->right.

#2

hello @garganshul151

no ,it will work only when replace is leaf node ,for all other case it will not.

consider this

we cannot delete orange node direclty.

#3

if the node to be deleted is orange node then what will happen to the node below it,black one,will it also be deleted? or attached again to tree

#4

it will attach again to the tree.
pls refer the deletion video again. all such cases are covered in detail
