    Question :: 3
    Which is efficient in respect to searching AVL tree or RED BLACK tree.

    Answer:
    RB-Trees are, as well as AVL trees, self-balancing. Both of them provide O(log n) lookup and insertion performance.
    In respect to searching AVL tree is efficient then Red-Black Tree because they are more rigidly balanced.. The path from the root to the deepest leaf in an AVL tree is at most ~1.44 lg(n+2), while in red black trees it's at most ~2 lg (n+1).
    But if your application required frequent insertions and deletions, then Red Black trees should be preferred over AVL tree.
