大数乘法取模模板。
AC代码：
#include <bits/stdc++.h>
using namespace std;
long long add(long long a, long long b, long long p)
{
long long res = 0;
while (b)
{
if (b & 1)
res = (res + a) % p;
a = (a * 2) % p;
b >>= 1;
}
return res % p;
}
int main()
{
long long a, b, p;
scanf("%lld%lld%lld", &a, &b, &p);
printf("%lld\n", add(a, b, p));
return 0;
}
