Triple Element Summation Solution

Problem Statement

Given a queue of integers and a target sum, find all unique triplets in the queue that sum up to the target value, with the constraint that each element can only be used once in each triplet.

Example 1

Input

Queue: [12, 4, 7, 9, 3, 5, 1], Target Sum: 22

Output

[[3, 7, 12]]

Explanation: One unique triplet [3, 7, 12] sums up to the target 22.

Example 2

Input

Queue: [2, 8, 6, 4], Target Sum: 14

Output

[[2, 4, 8]]

Explanation: The unique triplet [2, 4, 8] sums up to the target 14.

Constraints

The queue will contain at least three elements.
The target sum is a positive integer.
