The AVL Tree is essentially a binary search tree, which features: The first is a binary search tree. With a balance condition: the absolute value (equilibrium factor) of the height difference between left and right subtree of each node is 1 at most. # Include Data Structure and algorithm problems AVL binary balancing tree

http://www.51nod.com/onlineJudge/questionCode.html#!problemId=1770This is question B of this BSG Bss Geek Challenge . Set p (i, J) to indicate the number of nodes in the number of I, the height of the AVL tree is J . Well, for 1 P[I][J] + = P[k][j-1]*p[i-1-k][j-1]%mod;P[I][J] + = P[k][j-2]*p[i-1-k][j-1]%mod;P[I][J] + = P[k][j-1]*p[i-1-k][j-2]%mod;But this simulation isn^3of complexity. Obviously it's not going to work. ButJand thekthe scope is to beI

Recently the data structure of the bad, but holding a little niece really review not go in ... That's the end of the tree.There was no systematic understanding of the balance tree at the time.Specific gratitude is not affixed, carefully say how to adjust the balance of the binary treeIf the insertion breaks the original balance, the "Trouble Junction" is called the RR Insert, which is on the right side of the right subtree of the discovery, requiring RR rotation (right paddle)Make the following

How do I manage layers in a CAD drawing? After the designers have finished editing the CAD drawings, it is necessary to pay customers to view, but sometimes in order to facilitate the customer to better view the CAD drawings, you need to make the CAD drawing layer management, so it is convenient and fast to view, but i

The Caddy graphic software on the market is varied, both foreign and domestic software development is relatively mature, but the current CAD 3D drawing is still a little lacking. Here we recommend 10 very useful CAD drawing tools, which support both 2D and 3D, and most of them are free CAD drawing tools, there are also well-functional paid software. Click the fol

How do I draw a wedge in CAD? We all know that the CAD editor is a common CAD drawing tool in the CAD industry, but when we first use the CAD editor, CAD is in the graphic, not what we need, then when we need to draw in
