<p>如果数组是单调递增或单调递减的，那么它是 <strong>单调 </strong><em>的</em>。</p>
|
||
|
||
<p>如果对于所有 <code>i <= j</code>，<code>nums[i] <= nums[j]</code>，那么数组 <code>nums</code> 是单调递增的。 如果对于所有 <code>i <= j</code>，<code>nums[i]> = nums[j]</code>，那么数组 <code>nums</code> 是单调递减的。</p>
|
||
|
||
<p>当给定的数组 <code>nums</code> 是单调数组时返回 <code>true</code>，否则返回 <code>false</code>。</p>
