Compile a function. When n is an even number, call the function to calculate 1/2 + 1/4 +... + 1/n. When n is an odd number, call the function 1/1 + 1/3 +... +

There are many formulas in the history of Pi Pai, in which Gregory and Leibniz found the following formula:Pai = 1-1/3+1/5-1/7 (...)This formula is simple and graceful, but in the ointment, it converges too slowly.If we rounded up the two decimal places that kept it, then:Ac

refactoring. The following is a list of modified content: 1. Check whether the value of nextProjectile is nil at the beginning of the function. This means that our current touch event is happening in the shooting process. That is to say, the turret has shot a bullet. 2. Previously, we used a projectile local variable and added it to the current scenario. In this version, we added a member variable of nextP

is going to solve. The following example shows how to review the question:"Enter two numbers to obtain the maximum common number"Here, the question requires that it is unclear what the two numbers are. Is it an integer? Score? Real number? Plural? Such problems cannot be solved. Because the problem itself is not thorough and strict. When copying a question, you can also think about the specific requirements of the program and clarify the functions of the program. If necessary, you can further c
