17 . P1200 [USACO1.1]你的飞碟在这儿Your Ride Is He…

题目：这是洛谷的第17道题目，将输入的字符串提取出来，转换成小写的字符，进行乘法运算，然后比较两个数与47的求余即可。

源代码：

#include 
#include 
#include 
#include 

using namespace std;

#define MIDDLE 64
#define VALUE 47

int main()
{
    int sum1 = 1,sum2 = 1;
    string first, second;
    cin >> first;
    cin >> second;

    char * str1 = new char[first.size()];
    char * str2 = new char[second.size()];

    strcpy(str1, first.c_str());
    strcpy(str2, second.c_str());

    for (size_t i = 0; i < first.size(); i++)
        sum1 *= str1[i] - MIDDLE;
    
    for (size_t i = 0; i < second.size(); i++)
        sum2 *= str2[i] - MIDDLE;
    
    if (sum1%VALUE == sum2%VALUE)
        cout << "GO" << endl;
    else
        cout << "STAY" << endl;
    
    system("pause");
    return 0;
}
