Delete node from BST

#1


all test cases failed
where is it wrong ??

#2

your way of creating bst is not correct
i have done modification in your code

check them

if you have any doubt feel free to ask

#3

in line no 64 in your code
root->right = delete_node(root->right, replace->data);

why do we need to assign delete_node function into root->right, as it is already assigned so why do we need to do it here again ??

can u gve me any case where this LHS root->right is needed ???

#4

if we have only 3 nodes

  40
60 70

in this case root->right is important

#5

yess… but root ke right m pehle se (tree build ke samah se hi) right wale node ka address hoga
m reassign krne ki kya zarurat h ???

#6

wo delete ho sakta hai
us case me wo return NULL karega
so we have to store that in root->right
