2 * [2177] Find Three Consecutive Integers That Sum to a Given Number
3 *
4 * Given an integer num, return three consecutive integers (as a sorted array) that sum to num. If num cannot be expressed as the sum of three consecutive integers, return an empty array.
5 *  
6 * Example 1:
7 * 
8 * Input: num = 33
9 * Output: [10,11,12]
10 * Explanation: 33 can be expressed as 10 + 11 + 12 = 33.
11 * 10, 11, 12 are 3 consecutive integers, so we return [10, 11, 12].
12 * 
13 * Example 2:
14 * 
15 * Input: num = 4
16 * Output: []
17 * Explanation: There is no way to express 4 as the sum of 3 consecutive integers.
18 * 
19 *  
20 * Constraints:
21 * 
22 * 	0 <= num <= 10^15
23 *
