Sometimes, when I want to solve a problem, a solution comes to me and when I think about its asymptotics(The number of operations performed by the program or the big $$$O$$$), I understand that the solution will not work, but after looking at the solutions of other users, I see that my idea was correct. I don't post the solution right away because I'm afraid of unnecessary attempts. So answer the question: How many maximum operations can be performed in one second(C++)?

UPD: Thanks to everyone who helped!
