lateral thinking questions and answers

Question 1: "There are two doors in front of you, one of which contains hidden treasures, but if you accidentally break into another door, you can only die slowly ......".There are two people behind these two doors. Both of them know which door has a treasure and which one is good at death. But the two men only tell the truth, one person speaks only false words. Who tells the truth? It depends on whether you have the intelligence to find out. The game rule is that you can only ask one question t

A tightrope walker, who experiences pleasure in stimulation. Think with questions and spark sparks on the issue. Or to answer questions, or to answer questions, you may never see them all, but you can always break through a little bit. The key to the fact is to face the problem, how do I think? String interning is a topic worthy of thought, and with

, the next () method of the iterator throws a Concurrentmodificationexception exception.Concurrent containers support concurrent traversal and concurrent updates.The main classes are Concurrenthashmap, copyonwritearraylist and Copyonwritearrayset, read this article to understand How to avoid concurrentmodificationexception.8. What is the Executors class?Executors provides some tool methods for the Executor,executorservice,scheduledexecutorservice,threadfactory and callable classes.Executors can

keep the original base implementation. We can just inherit from it and rewrite the methods we need. Read the Java futuretask example to learn how to use it.7. What is the implementation of concurrent containers?Java collection classes are fast failures, which means that when a collection is changed and a thread iterates through the collection using Iterators, the next () method of the iterator throws a Concurrentmodificationexception exception.Concurrent containers support concurrent traversal

solves this problem for us. After the online pool submits the callable task, a future object is returned, using which we can know the status of the callable task and get the result of the execution callable returned. The future provides a get () method so that we can wait for callable to end and get its execution results.Read this article to learn more about the callable,future example. 6. What is Futuretask?Futuretask is a fundamental implementation of the future, and we can use it with execut

Usually we do not need to use the Futuretask class, it becomes very useful when we intend to rewrite some methods of the future interface and keep the original base implementation. We can just inherit from it and rewrite the methods we need. Read the Java futuretask example to learn how to use it.7.

simple, it is very appropriate to use the Atari game to test reinforcement learning. The application scenario can be described as: on the discrete timeline, each moment you can get the current game screen, choose to send a command to the game console (up and down, fire, etc.), and then get a feedback (reward). There is no way to use traditional methods directly due to the large state space of the reinforcement learning based on the primitive pixels. Thus, in 2013 DeepMind proposed the deep rein

Please design an algorithm to find one of them.A good chip indicates the maximum number of times you have used it.When comparing a good chip with other chips, we can correctly tell whether the other chip is good or bad.When the chip is compared with other chips, it will randomly give good or bad information.
