这道题说是爱丽丝和鲍勃在玩一个除数游戏，这爱丽丝和鲍勃估计就相当于我们的小明和小红，或者是李雷和韩梅梅之类的吧，经常出现啊。说是最初有一个数字N，每次每个人选一个小于N且能整除N的数字x，并将N替换为 N-x，依次进行，直到某个人没法进行了，则算输了。现在给个任意的N，且爱丽丝先走，问爱丽丝能否赢得游戏。先来分析一个下得到什么数字的时候会输，答案是当N变成1的时候，此时没法找到小于N的因子了，则输掉游戏。博主看到题后的第一个反应就是用递归，因为调用递归得到的结果是对手的胜负，若递归返回 false，则说明当前选手赢了，反之则当前选手输了。但是递归的方法不幸超时了，因为有大量的重复计算在里面，我们需要缓存这些中间变量，以避免重复计算，可以使用递归加记忆数组来做，也可以使用迭代的写法，那么就变成动态规划 Dynamic Programming 了。这里的 dp 数组定义很直接，dp[i] 表示起始数字为i时爱丽丝是否会赢，大小为 N+1，更新时从2开始就行，因为0和1都是 false，从2更新到N，对于每个数字，都从1遍历到该数字，找小于该数的因子，不能整除的直接跳过，能整除的看 dp[i-j] 的值，若为 false，则 dp[i] 更新为 true，并 break 掉即可，参见代码如下：, 其实这道题的终极解法就一行，直接判断奇偶即可，若N是偶数爱丽丝一定能赢，奇数一定会输。博主大概讲一下原因吧，前面提到过了，若某个人拿到了1，则表示输了，所以当拿到2的时候，一定会赢，因为取个因数1，然后把剩下的1丢给对手就赢了。对于大于2的N，最后都会先减小到2，所以其实这个游戏就是个争2的游戏。对于一个奇数N来说，小于N的因子x一定也是个奇数，则留给对手的 N-x 一定是个偶数。而对于偶数N来说，我们可以取1，然后变成一个奇数丢给对手，所以拿到偶数的人，将奇数丢给对手后，下一轮自己还会拿到偶数，这样当N不断减小后，最终一定会拿到2，所以会赢，参见代码如下：, https://github.com/grandyang/leetcode/issues/1025, https://leetcode.com/problems/divisor-game/, https://leetcode.com/problems/divisor-game/discuss/274608/Simple-DP-Java-Solution, https://leetcode.com/problems/divisor-game/discuss/296784/Come-on-in-different-explanation-from-others, 1227.
