暴力出来,竟然眼花了以为sg(i) = i啊....看表要认真啊!!!
#include <cstdio> #include <cstring> #include <iostream> using namespace std; #define LL __int64 int dp[10001]; int sg(int x) { int flag[10001],temp,i; if(dp[x] >= 0) return dp[x]; memset(flag,0,sizeof(flag)); for(i = 1;i <= x;i ++) { temp = sg(x-i); flag[temp] = 1; } for(i = 1;i < x;i ++) { temp = sg(i)^sg(x-i); flag[temp] = 1; } for(i = 0;;i ++) if(!flag[i]) return dp[x] = i; } int main() { int n,m,i,ans,t; scanf("%d",&t); while(t--) { scanf("%d",&n); ans = 0; for(i = 0;i < n;i ++) { scanf("%d",&m); if(m%4 == 0) m --; else if((m+1)%4 == 0) m ++; ans ^= m; } if(ans) printf("Alice\n"); else printf("Bob\n"); } return 0; }
