I haven't done as much as I did at the beginning these days . The problem becomes more and more difficult , It takes a long time to work out a problem . Sometimes it takes hours to understand a point without understanding it . For example, I made a KMP The topic , use cstdio Overtime , use stdio.h It's over , It's too metaphysical . Speaking of kmp,kmp The core of is seeking next Array , adopt next Array characteristics to solve problems .
Recently, I have realized some of my shortcomings in the process of making questions , For example, you can't write code quickly , Sometimes I have to look at the template , In the process of writing code, you must write your own handwriting instead of copying the template directly , This understanding of knowledge can also be reviewed , Can also maintain the ability to write code .
The speed of doing questions is still too slow , Increase the speed as much as possible .
