Good morning. Dear Teachers I am glad to be here for this interview.
My name is Zhanzeye, 21 years old,I come from AnHui,Anqing. I am going to graduate from the information and computer engineering department of Northeast Forestry University in july, 2020.
In the past three years I have been preparing for the postgraduate recommendation.
Now all my hard work has got a result since I have a chance to be here.
\^\ 和a 连读 发d So I just feel a little bit nervous, because this is my first time to have such an interview.
In the past three years, I have learnt some basic knowledge of software engineering.
For example, from the course of software architecture , I got to know software design pattern.
When I learnt more about this field. I became more interested in it.
Apart from textbooks, I borrowed many relevant ones from our library to read, such as data structure and network of computer
I really enjoy my journey when reading and absorbing the information from these fascinating works.
In addition to reading books, I also like browsing through some journals in 专业领域 on a daily basis so that I can keep an eye on the latest news and findings in my area.
My passion in software is the reason why I would like to pursue my further study in this field. Owing to my
diligence and persistence, I could concentrate on my study and I believe that Icould eventually succeed.
Floyd 算法是一种利用动态规划的思想、计算给定的带权图中任意两个顶点之间最短路径的算法。相比于重复执行多次单源最短路算法,Floyd 具有高效、代码简短的优势,在解决图论最短路题目时比较常用。
我们用 dp[k][i][j] 表示 i 到 j 能经过 1~ k 的点的最短路。那么实际上dp[0][i][j] 就是原图,如果 i, j之间存在边,那么 i , j之间不经过任何点的最短路就是边长,否则,i, j之间的最短路为无穷大。
那么对于 i, j 之间经过 1 ~ k 的最短路 dp[k][i][j] 可以通过经过 1 ~ k - 1 的最短路转移过来。
dp[k - 1][i][j]。dp[k - 1][i][k] + dp[k - 1][k][j]。所以就有转移
$\displaystyle dp[k][i][j] = min(dp[k - 1][i][j], dp[k - 1][i][k] + dp[k - 1][k][j])$

SPFA(Shortest Path Faster Algorithm)算法是单源最短路径的一种算法,通常被认为是 Bellman-ford 算法的队列优化,在代码形式上接近于宽度优先搜索 BFS,是一个在实践中非常高效的单源最短路算法。
在 SPFA 算法中,使用 d[i] 表示从源点到顶点 i 的最短路,额外用一个队列来保存即将进行拓展的顶点列表,并用 inq[i] 来标识顶点 i 是不是在队列中。
<u,v>权值为 w,若 d[u] + w < d[v],则最终 d 数组就是从源点出发到每个顶点的最短路距离。如果一个顶点从没有入队,则说明没有从源点到该顶点的路径。
The past several years have witnessed a booming economy in China. However, it is increasingly difficult for college undergraduates to find a decent job.
There are several factors contributing to this social phenomenon. To begin with, the job market is getting gloomy and competition is becoming fierce.
Moreover, the expectations of employment play an important part. A large number of graduates tend to give first priority to earnings and aim for well-paid position in foreign companies or big banks.
Last but not least, many employers do require job applicants to have a degree relate to the job.
One has to have additional education to get an edge. Education is indeed a worthwhile investment in the future.
