In 1989, the program for calculating the number of Pi fit into 200 lines of code (strongly depends on the curvature of the hands of the programmer) and was run on 512 kilobytes of operatives. Now the project in the visual studio takes 15 meters and asks for at least 20 meters of operatives. Progress pancake. People, why do you need a library just for the sake of calculating the maximum in the array?
