Consider integer numbers from 0 to n - 1 written down along the circle in such a way that the distance between any two neighboring numbers is equal (note that 0 and n - 1are neighboring, too).

Given n and firstNumber, find the number which is written in the radially opposite position to firstNumber.

Example

For n = 10 and firstNumber = 2, the output should be
circleOfNumbers(n, firstNumber) = 7.

我的解答：

def circleOfNumbers(n, firstNumber):

    return (firstNumber+n/2) % n
我的解法和排名第一的大佬写的一样....哈哈哈

膜拜大佬
