# Discussion on Dynamic Programming

The current series related to "dynamic programming" on the official account include: "dynamic programming - path problem" which has been completed and "dynamic programming - knapsack problem" which is being updated. This is a series of articles that assume you have some knowledge of "dynamic programming." However, in fact, there may be many students who are new to algorithms and are still at the stage of only using "naive/violent solutions" to solve algorithm problems, and do not know much about "dynamic programming". That's why I dug it up. It's probably me...

# PAT_ Class A _1147 HEAPS

For the complete binary tree, an array can be used to store its hierarchical sequence, and then functions ismaxHeap and isminHeap are used to determine whether the complete binary tree is a large root Heap or a small root Heap respectively. If neither is the case, output NOT Heap, and then use PostTraverse to perform post-order traversal of the complete binary tree. The output node can be accessed when the node.

Involvement refers to the phenomenon that a society (cultural model), after reaching a certain form at a certain stage of development, becomes stagnant and difficult to be transformed into another advanced mode, thus locking itself in a low-level state and going round and round.

# To JAVA small white, sorting out a set of simple programming algorithm can be used!!

Precipitation, sharing, growth, let oneself and others can gain! ? Introduction How close is mathematics to programmers? Whether it's an Ifelse or a for loop, code is a concrete implementation of mathematical logic. So the programmer who writes code is almost inseparable from math, with varying degrees of difficulty. That math is bad can't write code ?? No, you can also write code, you can write more CRUD out. Well, you don't have to think it's...

# Common algorithms for backtracking

From n distinct elements, any m distinct elements are arranged in a row in a certain order, which is called a permutation of m elements taken from n distinct elements. The number of all permutations of m(m≤n) elements taken from n different elements is called the number of permutations of m elements taken from n different elements, which is expressed by the symbol A(n, m). In addition, 0! = 1

# Look at the problem of "symmetric binary tree" from macroscopic point of view

The title describes this as "JZ 58 Symmetric Binary Tree" on "Niuke.com", with difficulty as "Difficult". Tag: "Sword Offer", "Binary Tree", "Sequential Traversal", "Iteration", "Recursion" Description: Please implement a function to determine if a binary tree is symmetric. Note that if a binary tree is the same as the image of the binary tree, define it as symmetric. Example 1 {Code... } Example 2 {Code... } Requirement: Time: 1 s vacant...
