Some third-party Libraries add the class of the system libraryCategory, In this case, you need to use the compilation parameters:-ObjcIn this way, the extension method for the system class in the third-party library can be used in the project.

Euler discovered the remarkable quadratic formula: N2 +N+ 41 It turns out that the formula will produce 40 Primes for the consecutive valuesN= 0 to 39. However, whenN= 40,402 + 40 + 41 = 40 (40 + 1) + 41 is divisible by 41, and certainly whenN= 41,
