In a AVL tree, the heights of the subtrees of any node differ by at the most one; If at any time they differ by more than one, the rebalancing is the done to restore this property. Figures 1-4 illustrate the rotation rules.
Now given a sequence of insertions, you is supposed to the root of the resulting AVL tree.Input Specification:Each inpu

, because my code enumeration to 1000000000 takes more than 30 seconds, online there are many other methods, but mostly C + + implementation. This also reflects the great advantages of CPP in solving algorithmic contests, and there are places where we can improve such as the first number of 2,4,6,8,5 does not need us to fold, because they are certainly not prime. So these places can be optimized, but my current code structure seems to be unable to do
