+<p>给定一个包含小写英文字母的字符串&nbsp;<code>s</code> 和一个整数&nbsp;<code>k</code>。</p>
+
+<p>你的任务是构造一个新的字符串，其中只包含在整个字符串&nbsp;<code>s</code> 中出现次数 <strong>少于</strong> <code>k</code> 次的字符。新字符串中字符的顺序必须与 <code>s</code> 中的 <strong>顺序相同</strong>。</p>
+
+<p>返回结果字符串。如果没有字符满足，返回一个空字符串。</p>
+
+<p>注意：出现次数少于 <code>k</code> 次的字符的每次出现都被保留。</p>
+
+<p>&nbsp;</p>
+
+<p><strong class="example">示例 1：</strong></p>

+<p><span class="example-io"><b>输出：</b>"dbb"</span></p>
+
+<p><strong>解释：</strong></p>
+
+<p><code>s</code>&nbsp;中字符出现的频率：</p>

+
+## 解法
+
+<!-- solution:start -->
+
+### 方法一：计数
+
+我们先遍历字符串 $s$，统计每个字符出现的频率，记录在哈希表或数组 $\textit{cnt}$ 中。
+
+然后再遍历字符串 $s$，将出现次数少于 $k$ 的字符添加到结果字符串中，最后返回结果字符串。
+
+时间复杂度 $O(n)$，其中 $n$ 是字符串 $s$ 的长度。空间复杂度 $O(|\Sigma|)$，其中 $\Sigma$ 是字符集大小。

+## Description
+
+<!-- description:start -->
+
+<p>You are given a string <code>s</code> consisting of lowercase English letters and an integer <code>k</code>.</p>
+
+<p>Your task is to construct a new string that contains only those characters from <code>s</code> which appear <strong>fewer</strong> than <code>k</code> times in the entire string. The order of characters in the new string must be the <strong>same</strong> as their <strong>order</strong> in <code>s</code>.</p>
+
+<p>Return the resulting string. If no characters qualify, return an empty string.</p>
+
+<p>Note: <strong>Every occurrence</strong> of a character that occurs fewer than <code>k</code> times is kept.</p>
+
+<p>&nbsp;</p>
+<p><strong class="example">Example 1:</strong></p>
+
+<div class="example-block">
+<p><strong>Input:</strong> <span class="example-io">s = &quot;aadbbcccca&quot;, k = 3</span></p>
+
+<p><strong>Output:</strong> <span class="example-io">&quot;dbb&quot;</span></p>
+
+<p><strong>Explanation:</strong></p>
+
+<p>Character frequencies in <code>s</code>:</p>
+
+<ul>
+	<li><code>&#39;a&#39;</code> appears 3 times</li>
+	<li><code>&#39;d&#39;</code> appears 1 time</li>
+	<li><code>&#39;b&#39;</code> appears 2 times</li>
+	<li><code>&#39;c&#39;</code> appears 4 times</li>
+</ul>
+
+<p>Only <code>&#39;d&#39;</code> and <code>&#39;b&#39;</code> appear fewer than 3 times. Preserving their order, the result is <code>&quot;dbb&quot;</code>.</p>
+</div>
+
+<p><strong class="example">Example 2:</strong></p>
+
+<div class="example-block">
+<p><strong>Input:</strong> <span class="example-io">s = &quot;xyz&quot;, k = 2</span></p>
+
+<p><strong>Output:</strong> <span class="example-io">&quot;xyz&quot;</span></p>
+
+<p><strong>Explanation:</strong></p>
+
+<p>All characters (<code>&#39;x&#39;</code>, <code>&#39;y&#39;</code>, <code>&#39;z&#39;</code>) appear exactly once, which is fewer than 2. Thus the whole string is returned.</p>
+</div>
+
+<p>&nbsp;</p>
+<p><strong>Constraints:</strong></p>
+
+<ul>
+	<li><code>1 &lt;= s.length &lt;= 100</code></li>
+	<li><code>s</code> consists of lowercase English letters.</li>
+	<li><code>1 &lt;= k &lt;= s.length</code></li>
+</ul>

+
+## Solutions
+
+<!-- solution:start -->
+
+### Solution 1: Counting
+
+First, we iterate through the string $s$ and count the frequency of each character, storing the results in a hash table or array $\textit{cnt}$.
+
+Then, we iterate through the string $s$ again, adding characters whose frequency is less than $k$ to the result string. Finally, we return the result string.
+
+The time complexity is $O(n)$, where $n$ is the length of the string $s$. The space complexity is $O(|\Sigma|)$, where $\Sigma$ is the size of the character set.
