Find Unique Sums

Implementation of a job interview assignment.

Usage

from sums import pairs

pairs([4, 23, 65, 67, 24, 12, 86])

Implementation Notes

Algorithmic complexity will be O(n^2\log n) - the second n comes from the complexity of dictionary/set insertions.

NumberPair makes the implementation of test cases noisy - given more time I'd probably either remove it, or replace the __eq__ implementation.

There is no "script" version - the assignment asks for a library call, and I'd have to invent a text format for this.
