<p>Given an array of integers <code>arr</code>, replace each element with its rank.</p>
|
|
|
|
<p>The rank represents how large the element is. The rank has the following rules:</p>
|
|
|
|
<ul>
|
|
<li>Rank is an integer starting from 1.</li>
|
|
<li>The larger the element, the larger the rank. If two elements are equal, their rank must be the same.</li>
|
|
<li>Rank should be as small as possible.</li>
|
|
</ul>
|
|
|
|
<p> </p>
|
|
<p><strong class="example">Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> arr = [40,10,20,30]
|
|
<strong>Output:</strong> [4,1,2,3]
|
|
<strong>Explanation</strong>: 40 is the largest element. 10 is the smallest. 20 is the second smallest. 30 is the third smallest.</pre>
|
|
|
|
<p><strong class="example">Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> arr = [100,100,100]
|
|
<strong>Output:</strong> [1,1,1]
|
|
<strong>Explanation</strong>: Same elements share the same rank.

|
|
|
|
<pre>

|
<ul>
|
|
<li><code>0 <= arr.length <= 10<sup>5</sup></code></li>
|
|
<li><code>-10<sup>9</sup> <= arr[i] <= 10<sup>9</sup></code></li>

</ul>
