Find all symmetric pairs in an array of pairs

[breeze37]

Given an array of pairs of integers, find all symmetric pairs, i.e., pairs that mirror each other. For instance, pairs (x, y) and (y, x) are mirrors of each other.

For example

Input: {3, 4}, {1, 2}, {5, 2}, {7, 10}, {4, 3}, {2, 5}

Output:

{4, 3} | {3, 4} {2, 5} | {5, 2}
