Why the below pseudo code where x is a value, wt is weight factor and t is root node can’t insert?

[answerhappygod]

WeightBalanceTreeNode insert(int x, int wt, WeightBalanceTreeNode k) :
 
if (k == null)
k = new WeightBalanceTreeNode(x, wt, null, null)
else if (x < t.element) :
 
k.left = insert (x, wt, k.left)
if (k.left.weight < k.weight)
k = rotateWithRightChild (k)
 
else if (x > t.element) :
 
k.right = insert (x, wt, k.right)
if (k.right.weight < k.weight)
k = rotateWithLeftChild (k)
a) when x>t. element Rotate-with-left-child should take place and vice versa
b) the logic is incorrect
c) the condition for rotating children is wrong
d) insertion cannot be performed in weight balanced trees
