快读

int read() {
    int x = 0, f = 1;
    char c = getchar();
    while (c < 48 || c > 57) { if (c == '-') f = ~f + 1; c = getchar(); }
    while (c >= 48 && c <= 57) { x = (x << 3) + (x << 1) + (c ^ 48); c = getchar(); }
    return f * x;
}

快写

void write(int x) {
    if (x < 0) putchar('-'), x = ~x + 1;
    if (x > 9) write(x / 10);
    putchar(x % 10 + '0');
}
void write(int x, char c) {
    write(x);
    putchar(c);
}

快速幂

int power(int a, int b/*, int p*/) {
    int ans = 1 /*% p*/;
    while (b >>= 1) {
        if (b & 1) ans = ans * a/* % p*/;
        a = a * a/* % p*/;
    }
    return ans;
}
