<p>给你一个整数数组 <code>salary</code> ，数组里每个数都是 <strong>唯一</strong> 的，其中 <code>salary[i]</code> 是第 <code>i</code> 个员工的工资。</p>
|
|||
|
|
|
|||
|
|
<p>请你返回去掉最低工资和最高工资以后，剩下员工工资的平均值。</p>

|
|
<p><strong>示例 1：</strong></p>
|
|||
|
|
|
|||
|
|
<pre><strong>输入：</strong>salary = [4000,3000,1000,2000]
|
|||
|
|
<strong>输出：</strong>2500.00000
|
|||
|
|
<strong>解释：</strong>最低工资和最高工资分别是 1000 和 4000 。
|
|||
|
|
去掉最低工资和最高工资以后的平均工资是 (2000+3000)/2= 2500
|
|||
|
|
</pre>
|
|||
|
|
|
|||
|
|
<p><strong>示例 2：</strong></p>
|
|||
|
|
|
|||
|
|
<pre><strong>输入：</strong>salary = [1000,2000,3000]
|
|||
|
|
<strong>输出：</strong>2000.00000
|
|||
|
|
<strong>解释：</strong>最低工资和最高工资分别是 1000 和 3000 。
|
|||
|
|
去掉最低工资和最高工资以后的平均工资是 (2000)/1= 2000
|
|||
|
|
</pre>
|
|||
|
|
|
|||
|
|
<p><strong>示例 3：</strong></p>
|
|||
|
|
|
|||
|
|
<pre><strong>输入：</strong>salary = [6000,5000,4000,3000,2000,1000]
|
|||
|
|
<strong>输出：</strong>3500.00000
|
|||
|
|
</pre>
|
|||
|
|
|
|||
|
|
<p><strong>示例 4：</strong></p>
|
|||
|
|
|
|||
|
|
<pre><strong>输入：</strong>salary = [8000,9000,2000,3000,6000,1000]
|
|||
|
|
<strong>输出：</strong>4750.00000
|
|||
|
|
</pre>
|
|||
|
|
|
|||
|
|
<p> </p>
|
|||
|
|
|
|||
|
|
<p><strong>提示：</strong></p>
|
|||
|
|
|
|||
|
|
<ul>
|
|||
|
|
<li><code>3 <= salary.length <= 100</code></li>
|
|||
|
|
<li><code>10^3 <= salary[i] <= 10^6</code></li>
|
|||
|
|
<li><code>salary[i]</code> 是唯一的。</li>
|
|||
|
|
<li>与真实值误差在 <code>10^-5</code> 以内的结果都将视为正确答案。</li>
|
|||
|
|
</ul>
