LeetCode ProblemFind the Winner of the Circular Game
There are n friends that are playing a game. The friends are sitting in a circle and are numbered from 1 to n in clockwise order. More formally, moving clockwise from the ith friend brings you to the (i+1)th friend for 1 <= i < n, and moving clockwise from the nth friend brings you to the 1st friend. The rules of the game are as follows: Given the number of friends, n, and an integer k, return the winner of the game. Example 1: Example 2: Constraints: Follow up: Could you solve this problem in linear time with constant space?
