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:
| Input | Output |
COMETQ HVNGAT |
GO |
ABSTAR USACO |
STAY |
PROGRAM NAME: ride
INPUT FORMAT
| Line 1: | An upper case character string of length 1..6 that is the name of the comet. |
| Line 2: | An upper case character string of length 1..6 that is the name of the group. |
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".

众所周知,每颗慧星后面都有不明飞行物（UFO）。这些不明飞行物常常在这里寻找忠诚的支持者。不幸的是,他们每次旅行只能带走一部分支持者。不过,他们总是通过一个聪明的方案让这群人提前知道谁会被带到哪个慧星上去：他们为每颗慧星取个名字,也给每个小组取个名, 这样就能够决定是否轮到该小组（你觉得谁会命名慧星呢？）。搭配方案的细节如下; 你的任务是编写一个带有小组和慧星的名字的程序,然后决定这个小组是否应被UFO带到慧星。
小组和慧星的名字通过下面的办法转换成数字：最终的数字是名字中字母所在字母表位置的乘积，即A等于1，Z等于26。 例如，组“USACO” 应该是21 * 19 * 1 * 3 * 15 = 17955。如果组的余数47与慧星的余数47相同，你就可以告诉这个组准备出发了! （注意“a除b的余数”是a被b除后剩下的数; 34除以10余4）。
编程读出慧星和小组的名字并指出以上两者是否相配，如果相配输出“GO”否则输出“STAY”。小组和慧星的名字是一串不含标点和空格的大写字母, 不超过6个字母。
