2016年省赛 G Triple Nimnim游戏,要求开始局面为先手必败,也就是异或和为0.如果n为奇数,二进制下最后一位只有两种可能1,1,1和1,0,0,显然异或和为1,所以方案数为0如果n为偶数,举个例子,14,二进制为1110,我们按位来拆1110==1000+100+101000=100+100+000也就是上一位的1可以拆成下一位的两个1和一个0,对于n在二进制下的每一个1都可以拆成3种情况(0都有三个位置可以选),所以为3^x,又因为如果每次0都选在同一个位置,就会出现0的情况,…
要点 不难发现问题转化成:n堆石子,每次最多选k堆最少选1堆然后拿走一个石子,谁先没子可拿谁败.本题中撤退不必考虑. 就是记笔记吧,类似nim的博弈,举例:\[k=3,n=4\]\[4堆石子分别是1.2.3.3\]全化为二进制\[01\]\[10\]\[11\]\[11\]然后每一位纵向加和,两位都是\(3\%(k+1)==0\),全能整除\((k+1)\)则后手胜,否则都是先手胜.PS:我只知道(k+1)应该与那个经典益智问题有关:共有若干火柴,每次最少拿1最多拿k,怎样先手必胜. int n…
