<p>Given a <strong>0-indexed</strong> string <code>s</code>, <strong>permute</strong> <code>s</code> to get a new string <code>t</code> such that:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>All consonants remain in their original places. More formally, if there is an index <code>i</code> with <code>0 <= i < s.length</code> such that <code>s[i]</code> is a consonant, then <code>t[i] = s[i]</code>.</li>
|
||
|
|
<li>The vowels must be sorted in the <strong>nondecreasing</strong> order of their <strong>ASCII</strong> values. More formally, for pairs of indices <code>i</code>, <code>j</code> with <code>0 <= i < j < s.length</code> such that <code>s[i]</code> and <code>s[j]</code> are vowels, then <code>t[i]</code> must not have a higher ASCII value than <code>t[j]</code>.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>Return <em>the resulting string</em>.</p>
|
||
|
|
|
||
|
|
<p>The vowels are <code>'a'</code>, <code>'e'</code>, <code>'i'</code>, <code>'o'</code>, and <code>'u'</code>, and they can appear in lowercase or uppercase. Consonants comprise all letters that are not vowels.</p>

<p><strong class="example">Example 1:</strong></p>
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
<strong>Input:</strong> s = "lEetcOde"
|
||
|
|
<strong>Output:</strong> "lEOtcede"
|
||
|
|
<strong>Explanation:</strong> 'E', 'O', and 'e' are the vowels in s; 'l', 't', 'c', and 'd' are all consonants. The vowels are sorted according to their ASCII values, and the consonants remain in the same places.

|
|
<pre>
|
||
|
|
<strong>Input:</strong> s = "lYmpH"
|
||
|
|
<strong>Output:</strong> "lYmpH"
|
||
|
|
<strong>Explanation:</strong> There are no vowels in s (all characters in s are consonants), so we return "lYmpH".
