快读的问题，改成这样就过了
```cpp
// 有理数取余
#include <iostream>
using namespace std;
using LL = long long;
const LL kM = 19260817;
LL a, b;
LL R() {
LL s = 0;
char c = getchar();
while (c < '0' || c > '9') {
c = getchar();
}
for (; c >= '0' && c <= '9'; c = getchar()) {
s = (s * 10 + c - '0') % kM;
}
return s;
}
int main() {
// freopen("P2613.in", "r", stdin);
// freopen("P2613.out", "w", stdout);
a = R(), b = R();
if (b == 0) {
cout << "Angry!";
return 0;
}
for (LL i = kM - 2; i; i >>= 1, b = b * b % kM) {
if (i & 1) {
a = a * b % kM;
}
}
cout << a;
return 0;
}
```
