Stability via Prefix Sums Pattern Visualizers

The Stability via Prefix Sums pattern is a recurring algorithmic shape that appears across coding interviews and competitive problems. Use it when the problem geometry matches its trigger conditions — recognizing the pattern collapses what looks like a hard problem into a familiar template. These visualizers trace Stability via Prefix Sums step-by-step on classics such as Counting Sort - Stable - Logic, so you can internalize the moves before you ever need them under pressure.
