Posted by pb03005073 at 2006-12-17 19:30:37 on Problem 2739
源代码如下:
#include <iostream>
#include <vector>
using namespace std;

vector<int> prime;

bool fprime(int n)
{
	for(int i=2;i<n;i++)
	{
		if(n%i==0)return 0;
	}
	return 1;
}
int solver(int n)
{
	int count=0;
	int begin=0;
	int x=0;
	int sum=0;
	
	while(prime.at(begin)<=n)
	{
		sum=0;
		x=begin;
		while(1)
		{
			sum+=prime.at(x);
			if(sum>n)
			{
				begin++;
				break;
			}
			else if(sum==n)
			{
				count++;
				begin++;
				break;
			}
			else 
				x++;
		}
	}
	return count;
}

void main()
{
	int n;	
	cin>>n;
	for(int i=2;i<10000;i++)
		if(fprime(i))prime.push_back(i);

	while(n)
	{
		cout<<solver(n)<<endl;
		cin>>n;
	}

}
