Interview Prompt
In ledger reconciliation the same amount lands on many lines and some entries are credits, so `nums` can hold duplicate and negative values. Given `nums` and a target `k`, return every trio of values taken from three distinct positions that sums to `k`.
Summary
Three numbers, one target.
