In 100 questions, how did I explain dynamic programming to my 5-year-old niece? | Denver annual essay

Dynamic Programming (DP) is a branch of operations research. It is the process of optimizing the decision-making process. In the early 1950s, THE American mathematician R.Bellman and others put forward the famous optimization principle when studying the optimization problem of the multi-stage decision process, thus creating the dynamic programming. Dynamic programming has a wide range of applications, including engineering...

25000 words metal surface after | the nuggets technology essay

A resume is not something to keep track of. It's something to let employers know your strengths. Have at ordinary times the charge service that makes a few modify resume, also calculate to have seen quite many resume. Many resumes have the following characteristics of the above similar resumes can be said that employers have seen countless copies, completely unable to catch your highlights. Unless you've worked at a big factory or have a good educational background or technology stack, it's pretty much luck getting an interview. ...

App security two and three things

Client anti cheating, is a very important, but it is very difficult to do a good job, spear and shield is always high, the devil is high ten zhangs. Now almost all apps are strongly related to the network, a lot of things displayed by the client are obtained from the server through the interface, of course, the server will also receive a large amount of data uploaded from the client, the two ends of two-way communication, it is easy to be intercepted by the third party, resulting in data theft,...

Inverse Polish representation to obtain four operations

The inverse Polish notation can be used to solve the problem of precedence operation of expressions. For example, for the infix expression 12 + (7-3) *2+9/3, the inverse Polish representation should be: 12 7 3-2 * +9 3 / +. The inverse Polish notation, though strange to look at, is not good for reading

Small white along the way, brush continuously for three years, talk about my algorithm learning experience

I came from a small white all the way, also brush in Leetcode for several years, also have some experience, also walked through a lot of pits, here to share a wave of my experience, please be patient to read it will certainly help. To tell the truth, want to improve their algorithm, I think is down-to-earth more hands to brush, brush more questions. But if you're a little white, that is, you connect common data structures like linked lists, trees, and...

Will change the world of graph algorithm - Dijkstra algorithm

Recently, I was reading the book "Algorithm Diagram", and I had a lot of feelings about the chapter "Dikstra algorithm". Dikstra algorithm is a very famous algorithm, which is one of the top ten algorithms to change the world. It is used to solve the single source shortest path problem of [weighting] [directed acyclic graph]. Note: The original version of dikstra's algorithm was only suitable for finding the shortest path between two vertices. Later, more common variants fixed a vertex as...

Remember a tear interview: Bytedance's interviewer beat me four times in a row

Bytedance this company, should be all autumn recruitment companies, the algorithm of the most attention to one, every interview will let you basically tear algorithm, today this article on the record was asked a few algorithm questions, and each algorithm I have given the optimal solution in detail, the following reenactment of the interview scene at that time. In most cases, the interviewer will ask a question that isn't that difficult, but don't...
