<p>在神秘的地牢中，<code>n</code> 个魔法师站成一排。每个魔法师都拥有一个属性，这个属性可以给你提供能量。有些魔法师可能会给你负能量，即从你身上吸取能量。</p>
|
|||
|
|
|
|||
|
|
<p>你被施加了一种诅咒，当你从魔法师 <code>i</code> 处吸收能量后，你将被立即传送到魔法师 <code>(i + k)</code> 处。这一过程将重复进行，直到你到达一个不存在 <code>(i + k)</code> 的魔法师为止。</p>
|
|||
|
|
|
|||
|
|
<p>换句话说，你将选择一个起点，然后以 <code>k</code> 为间隔跳跃，直到到达魔法师序列的末端，<strong>在过程中吸收所有的能量</strong>。</p>
|
|||
|
|
|
|||
|
|
<p>给定一个数组 <code>energy</code> 和一个整数<code>k</code>，返回你能获得的<strong> 最大 </strong>能量。</p>
