LPS / Prefix Function Pattern Visualizers

The LPS / Prefix Function 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 LPS / Prefix Function step-by-step on classics such as KMP (Knuth-Morris-Pratt) Algorithm, so you can internalize the moves before you ever need them under pressure.
