Finally, someone finished all the dynamic planning, linked list, binary tree and string required for the interview

For computer graduates , The algorithm post is basically **「 High salaries 」** The pronoun of .

However , Because of these years AI The direction is very hot , It seems that the algorithm post can't bear it anymore , Computer vision is a good example , The employment ratio of some companies has reached 32:1.

The problem of Zhihu also starts from **「 Is it worth entering 」 To 「 supply exceeds demand 」 Until then 「 The gods at dusk 」、「 The ashes 」、「 An elderly 」**, Year by year, exaggeration .

as everyone knows , Now the Internet factory interview , There will be a hand tearing code link in almost every round .

Among them, bytes are represented , Algorithm problems are notoriously difficult , An interview came down , Maybe I'll give it to you 2 Avenue LeetCode hard The subject of .

There are students in the interview , The previous project experience and basic knowledge can talk and laugh with the interviewer , When it comes to tearing the code by hand, it gets stuck , The atmosphere will be particularly embarrassing .

So the algorithm is a necessary part of it ！ stay Business questions in the interview can be summed up well , But the algorithm must rely on a solid foundation and brush questions . Algorithm foundation is not solid , It's not just sad about the interview , For code performance improvement 、 The control of programming languages is much weaker than others . therefore , Now the algorithm is not solid students , It's very difficult to pass the interview of a large factory .

In this case , I specially prepared two algorithm scribbling notes of a big man , I feel like I've found a treasure ！ Some of my friends may have found out , But we still can't help Amway , I'm afraid some of my friends didn't see it .

This note contains the author's brush LeetCode Hundreds of questions sorted out after the algorithm , Each problem is accompanied by a detailed problem solving process .

Many people say that the efficiency of data structure and algorithm is not high , It's very painful , With the summary of this note , It is self-evident that it helps the algorithm of school enrollment and social recruitment , I recommend it to you .

summary

The so-called technical ability is actually the ability to solve problems and learning ability , So no matter what stage you are in , Even higher stage , Constantly improving these two abilities is what you should always do .
