<p>In a mystic dungeon, <code>n</code> magicians are standing in a line. Each magician has an attribute that gives you energy. Some magicians can give you negative energy, which means taking energy from you.</p>
|
||
|
||
<p>You have been cursed in such a way that after absorbing energy from magician <code>i</code>, you will be instantly transported to magician <code>(i + k)</code>. This process will be repeated until you reach the magician where <code>(i + k)</code> does not exist.</p>
|
||
|
||
<p>In other words, you will choose a starting point and then teleport with <code>k</code> jumps until you reach the end of the magicians' sequence, <strong>absorbing all the energy</strong> during the journey.</p>
|
||
|
||
<p>You are given an array <code>energy</code> and an integer <code>k</code>. Return the <strong>maximum</strong> possible energy you can gain.</p>

<div class="example-block" style="
