 ## 题目描述
 
 <!-- description:start -->
 
-<p>You are given an integer array <code>timeReq</code> and an integer <code>splitTime</code>.</p>
+<p>给定一个整数数组&nbsp;<code>timeReq</code>&nbsp;和一个整数&nbsp;<code>splitTime</code>。</p>
 
-<p>In the microscopic world of the human body, the immune system faces an extraordinary challenge: combatting a rapidly multiplying bacterial colony that threatens the body&#39;s survival.</p>
+<p>在人体微观世界中，免疫系统面临着一项非凡的挑战：对抗快速繁殖的细菌群落，这对身体的生存构成威胁。</p>
 
-<p>Initially, only one <strong>white blood cell</strong> (<strong>WBC</strong>) is deployed to eliminate the bacteria. However, the lone WBC quickly realizes it cannot keep up with the bacterial growth rate.</p>
+<p>最初，只部署一个 <strong>白细胞</strong>（<strong>WBC</strong>）来消除细菌。然而，单独的白细胞很快意识到它无法跟上细菌的生长速度。</p>
 
-<p>The WBC devises a clever strategy to fight the bacteria:</p>
+<p>WBC制定了一种巧妙的策略来对抗细菌：</p>
 
 <ul>
-	<li>The <code>i<sup>th</sup></code> bacterial strain takes <code>timeReq[i]</code> units of time to be eliminated.</li>
-	<li>A single WBC can eliminate <strong>only one</strong> bacterial strain. Afterwards, the WBC is exhausted and cannot perform any other tasks.</li>
-	<li>A WBC can split itself into two WBCs, but this requires <code>splitTime</code> units of time. Once split, the two WBCs can work in <strong>parallel</strong> on eliminating the bacteria.</li>
-	<li><em>Only one</em> WBC can work on a single bacterial strain. Multiple WBCs <strong>cannot</strong> attack one strain in parallel.</li>
+	<li>第 <code>i</code> 个细菌菌株需要 <code>timeReq[i]</code> 个时间单位来被消除。</li>
+	<li>单个白细胞只能消除 <strong>一种</strong> 细菌菌株。之后，白细胞耗尽，无法执行任何其他任务。</li>
+	<li>一个白细胞可以将自身分裂为两个白细胞，但这需要&nbsp;<code>splitTime</code>&nbsp;单位时间。一旦分裂，两个白细胞就可以 <strong>并行</strong> 消灭细菌。</li>
+	<li>仅有一个白细胞可以针对一个单一细菌菌株工作。多个白细胞不能同时攻击一个菌株。</li>
 </ul>
 
-<p>You must determine the <strong>minimum</strong> time required to eliminate all the bacterial strains.</p>
+<p>您必须确定消除所有细菌菌株所需的 <strong>最短</strong> 时间。</p>
 
-<p><strong>Note</strong> that the bacterial strains can be eliminated in any order.</p>
+<p><strong>注意</strong>，细菌菌株可以按任何顺序消除。</p>

-<p>The elimination process goes as follows:</p>
+<p>消除过程如下：</p>
 
 <ul>
-	<li>Initially, there is a single WBC. The WBC splits into 2 WBCs after 2 units of time.</li>
-	<li>One of the WBCs eliminates strain 0 at a time <code>t = 2 + 10 = 12.</code> The other WBC splits again, using 2 units of time.</li>
-	<li>The 2 new WBCs eliminate the bacteria at times <code>t = 2 + 2 + 4</code> and <code>t = 2 + 2 + 5</code>.</li>
+	<li>最初，有一个白细胞。经过 2 个时间单位后，白细胞分裂成 2 个白细胞。</li>
+	<li>其中一个白细胞在&nbsp;<code>t = 2 + 10 = 12</code>&nbsp;时间内消除菌株 0。另一个白细胞使用 2 个单位时间再次分裂。</li>
+	<li>2 个新的白细胞消灭细菌的时间是 <code>t = 2 + 2 + 4</code> 和&nbsp;<code>t = 2 + 2 + 5</code>。</li>
