The main idea is to tell you to fix n courses, each course has a weight of w[i], in the K-day course to get k*w[i] of the learning points, give the curriculum and the relationship between the first course, to take the course must be completed prior to the course. Ask how many points you can learn.A very simple pressure DP (I also misled my teammates to write a two-dimensional t^t);Dp[s]: s binary is the maximum number of points that can be obtained in the selected course, in that state.If you le

language tightly linked together, once upon a while, many people think that seven cows choose Go language is a very bold decision. How should programmers choose the right programming language? How to learn effectively in the face of a new language? There is no correct programming language, only the appropriate language. Choosing a language requires a decision based on your understanding of the problem domain to be solved. Of course, this matter is also related to taste, different languages actu

Assume that's the dice is fair, that's means when you throw the dice, the probability of occurring any face is equal.For example, for a fair, and sided coin, the result is 3. Because When you first throw the coin and you'll definitely see a n
