At the beginning of the school, the multimedia in the school broke down a lot, except for the 12 new sets, the rest basically had problems. For two consecutive weeks, the service was mostly used for multimedia maintenance. It was very busy and tiring. Fortunately, the newly recruited Mr. Xu is still awesome, diligent, and intelligent. In the past two days, the projector has to be cleared several times. So I collected and sorted out various projector resetting methods. **********************

lamps, all of which have the same current through the lamp. To save money, you can replace some lights with a high-voltage bulb instead (the price of a light bulb that is at a high voltage, the number remains the number of the bulb being replaced). Now ask you to install these numbers of lights, at least how much money. #include parsing:Simple one-dimensional

recognize all colleage entities interacting with each other in order to achieve mutual interaction.The colleage abstract class is the parent category for all entities that you want to interact with.The Concretecolleage class is the practice of colleage, and every entity needs to know the middleman, but the entities don't need to know each other, just define their own behavior.The following is a specific code for the man-in-the-middle modeThe main function of the code is to simulate three light

Breadth-First search to find the shortest path problem, dealing with the following issues: Title: Given an array, the inside is full of positive integers. The number size indicates that this step can move up to several nodes backward. Total is to move from the first element of the array. Asked how to move, you can move to the last node with a minimum number of steps. For example: [3, 4, 2, 1, 3, 1] The initial state points to 3, which means that the next step is to move 1, or 2, or 3 lattices. T

a polymorphism mechanism. In the OO idea, polymorphism hides the specific implementation, so that the client can access the object without knowing the specific implementation but only its interface, which makes abstraction possible. 2. Relationship between Polymorphism and abstraction Let's use Wikipedia: Usually action is a mechanic and practice to reduce and factor out details so that one can focus on a few concepts at a time. That is, abstraction is a mechanism and practice that allows

not 10, because every number is different, so I should be 30." In this way, the third logologist will guess that his number is 30, but he does not. In the first round, no one has accurately deduced his number. This shows that our premise is incorrect, the number of the first logistician is not 10, so he can only be 50. Question 7: "You have one hundred bulbs in front of you, in a row ......" One hundred bulbs are arranged in a row. In the first round, you turn them on, and in the second

numbers are 20, 30, and 50 respectively.Assume that the number on the forehead of the second and third logistician is 20 and 30. If the number of the first logistician is 10, then the second logistician will see that the other two are 10, if one is 30, you will think: "I am either 20 or 40."The third logologist saw two other people, 10 and 20, and thought, "I am either 30 or 10, but I am not 10, because every number is different, so I should be 30."In this way, the third logologist will guess t

Test instructions given n types of light bulbs, each bulb gives its voltage V, the power cost K, the cost of each lamp C and the demand L, now by using a large voltage bulb to replace some of the small voltage bulb to reduce the total cost, to find the minimum cost.First of all, it is easy to prove that, for the minimum cost, it is possible to replace or replace

Are you still complaining about too few WIFI hotspots and unstable signals? In the future, if you have a light bulb, you will have wireless network signals, and the transmission speed will be as high as 1 Gbps, much higher than that of WIFI. This technology was invented by Herald Haas, a British university technician, and his team-the use of light to transmit data, often known as visible light communication VLC ). However, there is no obstacle to achi

The IT eternal in the world, Kostya understood it on the 7-th of January as he saw partially dead four-color garland . Now it has a goal to replace dead light bulbs, however his doesn ' t know how many light the for each color bulbs are. It is guaranteed this for each of four colors in least one light is working. It is known the Garland contains light bulbs of four colors:red, blue, yellow and green. The Garland is made as follows:if your take any four consecutive light bulbs then there won't be

I knew that there were two enemies.I'll go, what do you say if the enemy comes in 200? You either smoked or burned enough fire to burn yourself ...Dynasties in the development of human progress.
