输出一个位置 可以使左右两边之和相等

#include<iostream>using namespace std;int main(){int n,i,a[50],s,sn;while(cin>>n,n){s=0;for(i=1;i<=n;i++){cin>>a[i];s+=a[i];}sn=0;for(i=1;i<=n;i++){sn+=a[i];if(sn*2==s)break;}if(i==n+1)cout<<"No equal partitioning.\n";elsecout<<"Sam stops at position "<<i<<" and Ella stops at position "<<i+1<<".\n";}return 0;}
