Question: Examples of modifying existing data structures: Write a new method called SwapKeys ( n 1 , n 2 ) for a heap that takes two

Examples of modifying existing data structures:
Write a new method called SwapKeys (n1,n2) for a heap that takes two nodes and swaps
their keys.
Write a new method called FindBalance (n) for an AVL tree that given any node, returns the
height difference of its two sub-trees.
Write a new method called UpdateKey (n,i) for a heap that takes as input a node and
increments its key by i
