2177 - Find Three Consecutive Integers That Sum to a Given Number.

Medium

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.

Example 1:

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].

Example 2:

Input: num = 4

Output: []

Explanation: There is no way to express 4 as the sum of 3 consecutive integers.

Constraints:

  • 0 <= num <= 1015

  • Constructor Details

    • Solution

      public Solution()

  • Method Details

    • sumOfThree

      public long[] sumOfThree(long num)
