传说中的Google的第一题

传说是Google在发表在国外杂志上的题目，这里要说的是第一题。本博曾经解答过第三题，请看

http://www.51testing.com/?10851/action_viewspace_itemid_75367.html

1. Solve this cryptic equation, realizing of course that values for M and E could be interchanged. No leading zeros are allowed. （解答下面的隐藏等式，其中的M和E的值可以互换，但不允许第一位是0）
      WWWDOT - GOOGLE = DOTCOM

   最开始我看到的是中文翻译的，愣是没看懂题啥意思，多亏后来看到了原版，才知道这是一道代数题。

我的答案 W =8 D=7 O=4 T=4 G=1 L=0 E=2 C=6 M=2 

先验证一下该答案是不是正确。

从目前来看，答案倒是正确，但我现在想的是Google出这道题目的真正意义。实不相瞒，上面的答案是我试出来的，先假设几个数，然后回推得到的答案。很显然这个答案是正确的，但绝不是唯一的。我猜测Google的目的是让应试者自己通过编程，把所有的答案列出来。下面我就试试用C编程，把所有的可能穷举出来。

#include "stdio.h"

/* WWWDOT - GOOGLE = DOTCOM */
/* M and E could be interchanged */
/* w g d cannot equal to 0 */
/* w > g */
void main(void)
{
 int w=0, d, o, t, g, l, e, c, m;
 int wwwdot, google, dotcom;
 int googlm, dotcoe;
 FILE *fp = fopen("result.txt","a");
 
 for(w=2; w<=9; w++)  /* this line will be replaced by for loop */
 {
  for(d=1; d<=9; d++)
  {
   for(o=0; o<=9; o++)
   {
    for(t=0; t<=9; t++)
    {
     for(g=1; g<=8;g++)
     {
      for(l=0; l<=9; l++)
      {
       for(e=0; e<=9; e++)
       {
        
        wwwdot = w*100000 + w*10000 + w*1000 + d*100 + o*10 + t;
        google = g*100000 + o*10000 + o*1000 + g*100 + l*10 + e;
        
        m = (wwwdot-google) % 10;            //get m
        c = ((wwwdot-google) % 1000)/100;    //get c        

        dotcom = d*100000 + o*10000 + t*1000 + c*100 + o*10 + m;

        googlm = g*100000 + o*10000 + o*1000 + g*100 + l*10 + m;
        dotcoe = d*100000 + o*10000 + t*1000 + c*100 + o*10 + e;
        if((((wwwdot-google)==dotcom)) && ((wwwdot-googlm)==dotcoe))
         {
          fprintf(fp,"**********************\n");
          fprintf(fp,"w = %d, d= %d, o = %d, t = %d, g = %d, l = %d, e = %d, c = %d, m =%d \n", w,d,o,t,g,l,e,c,m);
         }
       }
      }
     }
    }
   }
  }
 }
 fclose(fp);
}

在Visual C++中运行，得到result.txt，该文件中列出了全部的可能。
