题目描述 Description
已知有一堆西瓜，请帮忙将这一堆西瓜分成两堆，已知每个西瓜的重量，现在要求分成两堆的西瓜的重量的差最小

输入描述 Input Description
第一行输入西瓜数量N (1 ≤ N ≤ 20)
第二行有N个数，W1, …, Wn (1 ≤ Wi ≤ 10000)分别代表每个西瓜的重量

输出描述 Output Description
输出分成两堆后的质量差

样例输入 Sample Input
5
5 8 13 27 14
样例输出 Sample Output
3

话说我没有强制类型转换咋就CE啦？

DEV-c++里面我编译过了呀！

#include<iostream>
#include<cmath>
using namespace std;

int n,w[10010],ans=0x7f7f7f7f;

void dfs(int t,int sum1,int sum2){
	if(t>n){
		ans=min(ans,(int)abs(sum1-sum2));
		return ;
	}
	dfs(t+1,sum1+w[t],sum2);
	dfs(t+1,sum1,sum2+w[t]);
	return ;
}

int main(){
	cin>>n;
	for(int i=1;i<=n;i++) cin>>w[i];
	dfs(1,0,0);
	cout<<ans;
	return 0;
}

/*
