<div class="ques-view"><p>Given a list of <span class="katex"><span class="katex-mathml"><math><mrow><mi>N</mi></mrow>N</math></span><span aria-hidden="true" class="katex-html"><span class="strut" style="height:0.68333em;"></span><span class="strut bottom" style="height:0.68333em;vertical-align:0em;"></span><span class="base textstyle uncramped"><span class="mord mathit" style="margin-right:0.10903em;">N</span></span></span></span> student records with name, ID and grade. You are supposed to sort the records with respect to the grade in non-increasing order, and output those student records of which the grades are in a given interval.</p>

<h3 id="input-specification-">Input Specification:</h3>
|
|
<p>Each input file contains one test case. Each case is given in the following format:</p>
|
|
<pre><code>N
|
|
name[1] ID[1] grade[1]
|
|
name[2] ID[2] grade[2]
|
|
... ...
|
|
name[N] ID[N] grade[N]
|
|
grade1 grade2
|
|
</code></pre><p>where <code>name[i]</code> and <code>ID[i]</code> are strings of no more than 10 characters with no space, <code>grade[i]</code> is an integer in [0, 100], <code>grade1</code> and <code>grade2</code> are the boundaries of the grade's interval. It is guaranteed that all the grades are <strong>distinct</strong>.</p>
|
|
<h3 id="output-specification-">Output Specification:</h3>
|
|
<p>For each test case you should output the student records of which the grades are in the given interval [<code>grade1</code>, <code>grade2</code>] and are in non-increasing order. Each student record occupies a line with the student's name and ID, separated by one space. If there is no student's grade in that interval, output <code>NONE</code> instead.</p>
