#include <bits/stdc++.h>
using namespace std;
const int N = 1e5;
int p;
int f[N];
bitset<N> unvis, g, h, tmp;
int main() {
scanf("%d", &p);
for (int i = 0; i < p; ++i) {
g.set(1ll * i * i % p);
unvis.set(i);
}
for (int o = 0; o < p; ++o) {
int cur = 1ll * o * o % p;
h = (g << cur) | (g >> (p - cur));
tmp = h & unvis;
unvis &= (~tmp);
for (int i = tmp._Find_first(); i != N; i = tmp._Find_next(i)) {
f[i] = o;
}
}
printf("%d\n", *max_element(f, f + p));
return 0;
}
这程序好像有点Bug，我给组数据试试？
