<p>Bob is stuck in a dungeon and must break <code>n</code> locks, each requiring some amount of <strong>energy</strong> to break. The required energy for each lock is stored in an array called <code>strength</code> where <code>strength[i]</code> indicates the energy needed to break the <code>i<sup>th</sup></code> lock.</p>
|
||||
|
||||
<p>To break a lock, Bob uses a sword with the following characteristics:</p>
|
||||
|
||||
<ul>
|
||||
<li>The initial energy of the sword is 0.</li>
|
||||
<li>The initial factor <code><font face="monospace">x</font></code> by which the energy of the sword increases is 1.</li>
|
||||
<li>Every minute, the energy of the sword increases by the current factor <code>x</code>.</li>
|
||||
<li>To break the <code>i<sup>th</sup></code> lock, the energy of the sword must reach <strong>at least</strong> <code>strength[i]</code>.</li>
|
||||
<li>After breaking a lock, the energy of the sword resets to 0, and the factor <code>x</code> increases by a given value <code>k</code>.</li>
|

</ul>

<p>You are given an integer array <code>nums</code> that represents a circular array. Your task is to create a new array <code>result</code> of the <strong>same</strong> size, following these rules:</p>
|
||||
For each index <code>i</code> (where <code>0 <= i < nums.length</code>), perform the following <strong>independent</strong> actions:
|
||||
|
||||
<ul>
|
||||
<li>If <code>nums[i] > 0</code>: Start at index <code>i</code> and move <code>nums[i]</code> steps to the <strong>right</strong> in the circular array. Set <code>result[i]</code> to the value of the index where you land.</li>
|
||||
<li>If <code>nums[i] < 0</code>: Start at index <code>i</code> and move <code>abs(nums[i])</code> steps to the <strong>left</strong> in the circular array. Set <code>result[i]</code> to the value of the index where you land.</li>
|

<li>If <code>nums[i] == 0</code>: Set <code>result[i]</code> to <code>nums[i]</code>.</li>
