assure you that if you are familiar with the contents of this book, you have a great opportunity to perform well in the interview. Another reason I like this book is that it is not filled with computer science theory and mathematics, but in the form of a very easy-to-understand question and answer format to tell the knowledge. It will tell you a variety of different solutions to the same interview question. I recommend you to buy a book, read it, master the concept of it, so that you can always

Before entering the subject, let's review the formula for calculating the charge and discharge time of the capacitor. Assume that the power supply vu is charging the capacitor C through the resistance R, and the v0 is the initial voltage value on the capacitor, VU is the voltage value after the capacitor is fully charged. If VT is the voltage value on the capacitor at any time t, the following formula can be obtained: Vt = V0 + (VU-V0) * [1-exp (-T/RC

gb8567--88Database Design Manual1 IntroductionHigh-quality database in the process of processing big data in the program or system is very important, so there are many requirements and provisions for database design. First of all, the database should have a good maintainability, flexibility, and the database of the algorithm logic must also have a certain degree of optimization, so that resources can be effectively utilized, and the processing time of the data will be shortened.1.1 Purpose of wr
