Today, when we look at algorithm analysis, we can see a problem where we can find the largest K value in a pile of data. The name is: design a group of N numbers, and determine the maximum value of K. This is a selection problem. Of course, there

In general, the interview process is not very difficult, but because this is my first interview, I still feel a bit uneasy ~ Because I am from the ACM training team of the school, it is rare that Alibaba is so qualified for ACM this year. In

In the previous article, I briefly talked about it. the differences between the. Net Value Type and the reference type are analyzed. The memory layout and implementation method of the reference type are analyzed. In the initial example, the
