<p>给你一个长度为 <code>n</code> 的整数数组 <code>pizzas</code>，其中 <code>pizzas[i]</code> 表示第 <code>i</code> 个披萨的重量。每天你会吃 <strong>恰好</strong> 4 个披萨。由于你的新陈代谢能力惊人，当你吃重量为 <code>W</code>、<code>X</code>、<code>Y</code> 和 <code>Z</code> 的披萨（其中 <code>W <= X <= Y <= Z</code>）时，你只会增加 1 个披萨的重量！体重增加规则如下：</p>

<ul>
|

<li>在 <strong><span style="box-sizing: border-box; margin: 0px; padding: 0px;">奇数天</span></strong>（按 <strong>1 开始计数</strong>）你会增加 <code>Z</code> 的重量。</li>

<p>You are given a string <code>s</code> consisting of digits.</p>
|
||||
|
||||
<p>Return the <strong>number</strong> of <span data-keyword="substring-nonempty">substrings</span> of <code>s</code> <strong>divisible</strong> by their <strong>non-zero</strong> last digit.</p>
|

|
||||
<p><strong>Note</strong>: A substring may contain leading zeros.</p>

<p><strong>Output:</strong> <span class="example-io">11</span></p>
|

|

<p><strong>Explanation:</strong></p>
|

|

<p>Substrings <code>"29"</code>, <code>"129"</code>, <code>"293"</code> and <code>"2936"</code> are not divisible by their last digit. There are 15 substrings in total, so the answer is <code>15 - 4 = 11</code>.</p>

<p>Substrings <code>"01"</code>, <code>"12"</code>, <code>"701"</code>, <code>"012"</code>, <code>"128"</code>, <code>"5701"</code>, <code>"7012"</code>, <code>"0128"</code>, <code>"57012"</code>, <code>"70128"</code>, <code>"570128"</code>, and <code>"701283"</code> are all divisible by their last digit. Additionally, all substrings that are just 1 non-zero digit are divisible by themselves. Since there are 6 such digits, the answer is <code>12 + 6 = 18</code>.</p>

<p>Only substrings that end with digit <code>'1'</code> are divisible by their last digit. There are 25 such substrings.</p>

<p>Given a string <code>s</code> of length <code>n</code> and an integer <code>k</code>, determine whether it is possible to select <code>k</code> disjoint <strong>special substrings</strong>.</p>
|
||||
|
||||
<p>A <strong>special substring</strong> is a <span data-keyword="substring-nonempty">substring</span> where:</p>
|
||||
|
||||
<ul>
|
||||
<li>Any character present inside the substring should not appear outside it in the string.</li>
|
||||
<li>The substring is not the entire string <code>s</code>.</li>
|
||||
</ul>
|
||||
|
||||
<p><strong>Note</strong> that all <code>k</code> substrings must be disjoint, meaning they cannot overlap.</p>
|
||||
|
||||
<p>Return <code>true</code> if it is possible to select <code>k</code> such disjoint special substrings; otherwise, return <code>false</code>.</p>
|
||||
|
||||
<p> </p>
|
||||
<p><strong class="example">Example 1:</strong></p>

|

|

|

<p><strong>Output:</strong> <span class="example-io">true</span></p>
|
||||
|
||||
<p><strong>Explanation:</strong></p>
|
||||
|
||||
<ul>
|
||||
<li>We can select two disjoint special substrings: <code>"cd"</code> and <code>"ef"</code>.</li>
|
||||
<li><code>"cd"</code> contains the characters <code>'c'</code> and <code>'d'</code>, which do not appear elsewhere in <code>s</code>.</li>
|
||||
<li><code>"ef"</code> contains the characters <code>'e'</code> and <code>'f'</code>, which do not appear elsewhere in <code>s</code>.</li>

|
||||
|
||||
<p><strong>Explanation:</strong></p>
|
||||
|
||||
<p>There can be at most 2 disjoint special substrings: <code>"e"</code> and <code>"f"</code>. Since <code>k = 3</code>, the output is <code>false</code>.</p>
