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 - 1
are 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 becircleOfNumbers(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
