Recommendation 101: Use extension methods to "add" methods to existing typesConsider how to have a new behavior for a sealed type. We used to create a wrapper class and then add a method to it, which doesn't look elegant at all. We might consider modifying the design, modifying the sealed type directly, and then publishing a new version for it, but it relies on you having all the source code. More often, we will take the approach of programming to API

Title: Determine how many primes there are between 101-200, and output all primes.
1. Procedure Analysis:
The method of determining primes: To remove 2 to sqrt (this number) by a number, if divisible, indicates that the number is not prime, and vice versa.
2. Program Source code:

signal is converted to a digital format, the sampling rate indicates how often the acoustic waveform sample is extracted to convert it into a digital signal.
In most cases, 44100hz is frequently used because it is the same as the sampling rate of CD audio.
