hey @manikjindal49
in this loop

if(root->data==k){
        return 0;/////////
    }

you are just returning 0 but your min value isn’t updated for the recursion fucntion

but if we return 0 thats what we want na to get the returned value as 0 it doesnot matter our min value changes or not bcz at last the value we want is 0
