实习了一下，并未发现代码有什么问题，求解

#include<bits/stdc++.h>
using namespace std;
int s[1000010],h[100010],f,a,b,n,m;
inline void read(int &x)
{
	x = 0;
	int f = 1;
	char s = getchar();
	while(s < '0' || s > '9')
	{
		if(s == '-') f = -1;
		s = getchar();
	}
	while(s >= '0' && s <= '9')
	{
		x = x * 10 + s - 48;
		s = getchar();
	}
	x *= f;
	return;
}
inline void write(int x)
{
	if(x < 0)
	{
		putchar('-');
		x *= -1;
	}
	if(x > 9) write(x / 10);
	putchar(x % 10 + 48);
	return;
}
int main()
{
	read(n),read(m);
	for(int i = 1;i <= n;i ++)
		read(s[i]);
	while(m --)
	{
		read(f);
		if(f == 1)
		{
			read(a),read(b);
			h[a] += b;
		}
		else
		{
			read(a);
			int ans = s[a];
			for(int i = 1;i * i <= a;i ++)
			{
				if(a % i == 0)
				{
					ans += h[i];
					if(i != a / i) ans += h[a / i];
				}
			}
			write(ans);
			putchar('\n');
		}
	}
	return 0;
