完数

<p class="p0" style="text-indent:36.0000pt;"> 完数的定义：如果一items大于<span>1</span><span>的正整数的所有因子之和等于它的本身，则称这items数是完数，比如</span><span>6</span><span>，</span><span>28</span><span>都是完数：</span><span>6=1+2+3</span><span>；</span><span>28=1+2+4+7+14</span><span>。本题的任务是判断两items正整数之间完数的items数。</span> </p>

<p class="p0"> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Page 一行输入一items<span>T</span><span>，代表有</span><span>T</span><span>组测试数据。接下来每行包含两items数，ａ，ｂ（</span><span>0</span><span>＜＝ａ＜＝ｂ＜＝</span><span>10000</span><span>）</span> </p>

<p class="p0"> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;请输出ａ和ｂ之间（包括ａ和ｂ）存在的完数items数。 </p>
