Your Ride Is Here

It is a well-known fact that behind every good comet is a UFO. These UFOs often come to collect loyal supporters from here on Earth. Unfortunately, they only have room to pick up one group of followers on each trip. They do, however, let the groups know ahead of time which will be picked up for each comet by a clever scheme: they pick a name for the comet which, along with the name of the group, can be used to determine if it is a particular group's turn to go (who do you think names the comets?). The details of the matching scheme are given below; your job is to write a program which takes the names of a group and a comet and then determines whether the group should go with the UFO behind that comet.

Both the name of the group and the name of the comet are converted into a number in the following manner: the final number is just the product of all the letters in the name, where "A" is 1 and "Z" is 26. For instance, the group "USACO" would be 21 * 19 * 1 * 3 * 15 = 17955. If the group's number mod 47 is the same as the comet's number mod 47, then you need to tell the group to get ready! (Remember that "a mod b" is the remainder left over after dividing a by b; 34 mod 10 is 4.)

Write a program which reads in the name of the comet and the name of the group and figures out whether according to the above scheme the names are a match, printing "GO" if they match and "STAY" if not. The names of the groups and the comets will be a string of capital letters with no spaces or punctuation, up to 6 characters long.

Examples:

COMETQ
HVNGAT

ABSTAR
USACO 

PROGRAM NAME: ride

INPUT FORMAT

NOTE: The input file has a newline at the end of each line but does not have a "return". Sometimes, programmers code for the Windows paradigm of "return" followed by "newline"; don't do that! Use simple input routines like "readln" (for Pascal) and, for C/C++, "fscanf" and "fid>>string".

SAMPLE INPUT (file ride.in)

COMETQ
HVNGAT

OUTPUT FORMAT

SAMPLE OUTPUT (file ride.out)

GO

这个平台的使用相当的麻烦，提交代码不是像POJ一样可以直接提交现成的代码，而是提交一个txt文件。

另外，代码的格式也不能乱写，必须按要求写好，里面的输入输出也必须是用文件读入读出的方式实现，总之两个字：麻烦！！！

我的代码：

/*

ID: topcoder3

PROG: ride

LANG: C++

*/

#include<fstream>

#include<string.h>

using namespace std;

ifstream fin("ride.in");

ofstream fout("ride.out");

int main()

{

         int a,b,i,l1,l2;

         char s1[10],s2[10];

         fin>>s1>>s2;

         a=1;

         b=1;

         l1=strlen(s1);

         l2=strlen(s2);

         for(i=0;i<l1;i++)

                   a=a*(s1[i]-'A'+1);

         for(i=0;i<l2;i++)

                   b=b*(s2[i]-'A'+1);

         if((a-b)%47)

                   fout<<"STAY"<<endl;

         else

                   fout<<"GO"<<endl;

         return 0;

}
