Linux和Windows平台都试过，样例和下载的数据都试过

怎么回事呀

#include <iostream>
using namespace std;
int c[26]={1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,4,1,2,3,1,2,3,4};
int cs(char x)
{
    if(x == ' ')return 1;
    return c[x-'a'];
}

int main(int argc, char **argv)
{
    string s;
    getline(cin,s);
    int a = 0;
    for(int i = 0; i < s.size(); i++)a += cs(s[i]);
    cout << a;
    return 0;
}
