I find a job very smooth, the first day in a pharmaceutical enterprise interview, the next day is a golf industry website for foreign-funded enterprises, although the two companies are required to interview standards in the undergraduate education.

Math.exp (x) to find the X-square of E 1.3. Trigonometric Functions The following functions receive an X in radians (radian) as an argument The code is as follows: Math.acos (x)

Customer Value Evaluation How is customer value evaluated? Let's take automotive customers for example. If a car is used normally, this problem may easily occur in five years. It is just like a middle-aged person who starts to hold the medicine box. After 8 or 10 years, you have to change the car. Otherwise, the repair cost is too high. It is better to replace a new car, just as we used a year 56-year mobile phone and repaired 200 yuan at a time, we will simply leave it unrepaired. Therefore,

A says they owe 1 billion, B says they owe 1.5 billion, and C says they owe 5 billion, some people will say, "Oh, why do you owe so little? I owe 12 billion

improve program writing efficiency and code quality. Only when you believe that unit testing is an important part of the programming process will it be promoted to design code that can withstand testing. In fact, it has become a trend to focus on the actions to be implemented by interfaces and classes, first writing test code and then program code. However, this article is a simple demonstration of unit testing, so the code used for testing actually exists. GolfI want to describe the whole proc
