Question
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
