<span style="font-size:28pt;"><span>•</span></span><span style="font-family:Arial;color:black;font-size:28pt;"> 福尔摩斯到某古堡探险，看到门上写着一个奇怪的算式：</span>

<span style="font-size:28pt;"><span>•</span></span><span style="font-family:Arial;color:black;font-size:28pt;"><span>&nbsp;&nbsp;&nbsp; </span></span><span style="font-family:Arial;color:black;font-size:28pt;">ABCDE * ? = EDCBA</span>

<span style="font-size:28pt;"><span>•</span></span><span style="font-family:Arial;color:black;font-size:28pt;"><span>&nbsp;&nbsp;&nbsp; </span></span><span style="font-family:宋体;color:black;font-size:28pt;">他对华生说：“</span><span style="font-family:Arial;color:black;font-size:28pt;">ABCDE</span><span style="font-family:宋体;color:black;font-size:28pt;">应该代表不同的数字，问号也代表某个数字！”</span>

<span style="font-size:28pt;"><span>•</span></span><span style="font-family:Arial;color:black;font-size:28pt;"><span>&nbsp;&nbsp;&nbsp; </span>华生：“我猜也是！”</span>

<span style="font-size:28pt;"><span>•</span></span><span style="font-family:Arial;color:black;font-size:28pt;"><span>&nbsp;&nbsp;&nbsp; </span>于是，两人沉默了好久，还是没有算出合适的结果来。</span>

<span style="font-size:28pt;"><span>•</span></span><span style="font-family:Arial;color:black;font-size:28pt;"><span>&nbsp;&nbsp;&nbsp; </span>把 </span><span style="font-family:Arial;color:black;font-size:28pt;">ABCDE </span><span style="font-family:宋体;color:black;font-size:28pt;">所代表的数字写出来。</span>
