In general, this reduces complexity of O(n^2) to O(n lgn).
From the benchmark we can see the performance gain:
Running benches/bench.rs (target/release/deps/bench-a5f1a4e304f6ce84) Gnuplot not found, using plotters backend 1000 events time: [443.46 µs 444.09 µs 444.76 µs] change: [-92.832% -92.611% -92.413%] (p = 0.00 < 0.05) Performance has improved.
