Delete Nodes from BST

[Prankur-Tewari-2574939259288733 (PRANKUR TEWARI)]

Not passing the test cases in both the case for taking the node from left or right in case of node having two children.
please tell my mistake
my code:

Coding Blocks IDE

[asaurabh_26 (logical coder)]

node *root=NULL;
this should come inside while loop
you have to intilize root=NULL in every testcase:
this is only problem
