job! That's it, I'm staying until now. But the wages have not risen a bit, although the project manager many years ago said that the increase in wages to the time is still not how to add. Poor now pay only 4k, see classmates outside 5,6,7k psychology inevitably some lost.Open year, many students have changed jobs of course, wages are certainly getting higher. Every time I hear it, I feel a little uncomfortable. But from their spoken language also feel that their technology is not very mature, p

I used to write some Python command line gadgets to simplify some repetitive work in my work. In this case, I had to traverse a directory. I had been writing recursion.ProgramTwo days ago, I discovered that there was a ready-made class library in Python.This function is OS.

sun shines, the first is the inevitable phenomenon of their own survival movement, shining all things, but it is derived from an objective meaning. So I think that as long as everyone is trying to improve the value of self-existence, then the whole human society's forward development has become inevitable.　　This is probably the law of man, and the law of biological evolution--the rule that no arbitrary preaching can be drowned or deceived. Some people say that the times are moving forward, but

Question: The random starting point of the connected undirected graph is randomly selected. You can repeatedly go through the vertex and ask how likely each vertex will not be passed. Ideas: One view is the DP question... But at the beginning, I got stuck. I wanted to calculate the probability of passing through each vertex first and then subtract this probability with 1. But since we can pass by again, we cannot judge whether it was the first time that we passed this vertex. Therefore, we shoul

Theory: Solution (backtracking ); The mouse moves in four directions: Top, left, bottom, and right. After each grid advances, the mouse chooses a direction to move forward.Return and select the next forward direction. In this way, test the four directions in sequence in the array until the exit is reached. This isThe basic questions returned.
