Fibonacci Series: The Fibonacci sequence, also known as the Golden Section, refers to a sequence of numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 、...... Mathematically, the Fibonacci sequence is defined as a recursive method: F (0) =0,f (1) =1,f (n) =f (n-1

Directory (?) [+] 1, balanced binary tree definition: Balanced binary trees (Balanced binary tree or height-balanced tree) are also known as AVL trees. It is either an empty tree, or a two-prong tree with the following properties: Its Saozi right

UVA_10518 It is easier to think of f (n) = f (n-1) + f (n-2) + 1, but if you can think of f (n) = 2 * F (n) -1 is not very easy. After reading the forum of ultraviolet A, I realized that it could have been represented like this, where F (n) is the

In fact, the whole chain is folded in half to get a tree. Also using a multiplier table, consider maintaining four values: Max,min,premax,submax, which can be solved.You can also use the line segment tree: The principal update and multiplication
