Solution: Find Symmetric Pairs in an Array
Explore how to find all symmetric pairs in an array by using hashing with a set in JavaScript. This lesson helps you implement a solution that checks for reversed pairs efficiently and understand its time and space complexity, strengthening your grasp of hashing concepts in practical coding scenarios.

Statement
Given an array of pairs, nums, find all the symmetric pairs from it.
A symmetric pair is defined as a pair [a, b] such that both [a, b] and [b, a] exist in the array.
If no symmetric pair is found, return an empty array.
Each symmetric pair should be returned once (you may return either
[a, b]or[b, a]).The output can be in any order.
