//递归快速幂
int qpow(int a, int n)
{
    if (n == 0)
        return 1;
    else if (n % 2 == 1)
        return qpow(a, n - 1) * a;
    else
    {
        int temp = qpow(a, n / 2);
        return temp * temp;
    }
}

//递归快速幂（对大素数取模）
#define MOD 1000000007
typedef long long ll;
ll qpow(ll a, ll n)
{
    if (n == 0)
        return 1;
    else if (n % 2 == 1)
        return qpow(a, n - 1) * a % MOD;
    else
    {
        ll temp = qpow(a, n / 2) % MOD;
        return temp * temp % MOD;
