C语言－耶稣门徒

<span style="font-family: Arial, Helvetica, sans-serif;">
</span>

<span style="font-family: Arial, Helvetica, sans-serif;">耶稣有15个门徒，其中有一个就是出卖耶稣的叛徒，</span>

<span style="font-family: Arial, Helvetica, sans-serif;">请用排除法找出这位叛徒：15人围坐一圈，从第一个开始报号：1，2，3，1，2，3……，</span>

<span style="font-family: Arial, Helvetica, sans-serif;">凡是报到“3”就退出圈子，最>后留在圈内的人就是出卖耶稣的叛徒，找出它原来的序号。</span>
