Algorithms

Given an integer <code>num</code>, return three consecutive integers (as a sorted array) that sum to <code>num</code>. If <code>num</code> cannot be expressed as the sum of three consecutive integers, return an empty array.

&nbsp;
Example 1:

<pre>
Input: num = 33
Output: [10,11,12]
Explanation: 33 can be expressed as 10 + 11 + 12 = 33.
10, 11, 12 are 3 consecutive integers, so we return [10, 11, 12].
</pre>

Example 2:

<pre>
Input: num = 4
Output: []
Explanation: There is no way to express 4 as the sum of 3 consecutive integers.
</pre>

&nbsp;
Constraints:

<ul>
	<li><code>0 &lt;= num &lt;= 1015</code></li>
</ul>

给你一个整数&nbsp;<code>num</code>&nbsp;，请你返回三个连续的整数，它们的&nbsp;和&nbsp;为&nbsp;<code>num</code>&nbsp;。如果&nbsp;<code>num</code>&nbsp;无法被表示成三个连续整数的和，请你返回一个 空&nbsp;数组。

&nbsp;

示例 1：

<pre>输入：num = 33
输出：[10,11,12]
解释：33 可以表示为 10 + 11 + 12 = 33 。
10, 11, 12 是 3 个连续整数，所以返回 [10, 11, 12] 。
</pre>

示例 2：

<pre>输入：num = 4
输出：[]
解释：没有办法将 4 表示成 3 个连续整数的和。
</pre>

&nbsp;

提示：

<ul>
	<li><code>0 &lt;= num &lt;= 1015</code></li>
</ul>
