some guidance, I understand it. In fact, I have been thinking that the conversion process of the decimal number should have a mathematical formula derivation, which leads to the constant conversion of the decimal number, if you focus on the binary number, it's hard to understand. (There may be a mathematical formula, but instead of looking for a formula 15-> 10-> 4, it is easier to understand the process of directly observing the changes of binary st

What are the differences between exit (0), exit (1), and exit (-1? When the process ends, the return value to the system is different. If your process is user, run echo $? You can see that the return value of your process is the value you set in the program, such as exit (0). Return

In the example 1 of parameter hypothesis test under 0-1 Population Distribution, I used the lookup table method to analyze how to perform the parameter hypothesis test. In this article, we will use the SPSS tool to directly calculate the results.
Speaking of SPSS, there are actually no strangers. I used SPSS 13 before and was not acquired by IBM at that time. No
