Stable Sorting
Preserve equal-element order.
What Is Stable Sorting
A stable sort keeps equal elements in their original relative order. If two records compare equal, the one that came first stays first.
Why It Matters
Stability matters when you sort by one field but want a previous order preserved for ties. For example, sort by city, keeping people alphabetical within each city.
