1, the real courage is to know that they are afraid, still meet the difficulties, know that there is difficulty, still accept the challenge.2, growth in addition to the face of pain, there is tolerance. People have a tendency to evade responsibility, so they often do not consciously blame others. Choose to blame or choose tolerance, in a certain sense, is the choice of mental illness or choose mental health. In essence, the essence of tolerance is selfish behavior, because his greatest value lie

back, and things might have changed (unpacking is not a simple boxing inverse process, it costs less than boxing, unpacking is the process of getting a pointer to the original value type contained in an object (data field), The pointer points to the unboxed part of the boxed instance and does not require any bytes to be copied in memory;Note When unpacking: 1. When a variable containing a reference to a boxed type instance is null, an exception is thrown (he has no room, no objects, you find a

the probability matrix of the final D step is b=b* (a^d). The b[i][j in the resulting B-matrix] is the probability that I will go through the D-step to J.Here is a small trick, in order to facilitate the calculation of the B matrix, can be initialized at the time only the No. 0 row of each node is set to 1/n (node I is still 0), indicating that the node J is selected as the starting point of the probability, so that the final calculated B-matrix only in the No. 0 row has the result, the other p

Here's the book. Random walk refers to the past performance, unable to predict the future development steps and direction. Your return on investment is at least equal to the rate of inflation, just to achieve breakeven. The rock theory argues that every investment tool has a solid pillar called "intrinsic value", whether it is ordinary stock or real estate. The value depends entirely on the price others are willing to pay. The higher the d

This problem card time card is relatively tight.At first, the direct BFS no doubt timed out, then thought to choose the starting point to traverse according to the conventional optimization idea of BFS.So we start with BFS once, this time the BFS is to choose this point for 1 and from the starting point to this point, the middle path point is all 0 points.By choosing this point, the length of this point to the end of the path can be determined.After that we put all the points to the lowest point

Test instructions: GBN recently planned to cross a forest, but he was very proud, so he decided to go only a few special roads, he intended to go only along the road (A, b) to meet the following conditions: There is a road from the start of the home, the path is shorter than all from A home. Your task is to calculate how many different home paths there are. Where the starting point is numbered 1 and the end number is 2.Idea: First from the end Dijkstra once, to find out each point u home of the

In fact, the principle of the implementation of the animation is relatively simple, the character walk when the state is divided into multiple pictures, and then use CSS3 animation properties of these images in series to form the character walking a

A fun interactive program, to use a function fflush, its role is to clean up the standard output stream, to stdout is to print data to the screen in a timely manner, a fact: the standard output is "line" for the unit, that is, hit \ n before printing data to the screen. This can cause delays. It is not visible on the Windows platform, it is changed to take effect in time.
