🧮 Fisher-Yates Algorithm

Invented by Ronald Fisher and Frank Yates in 1938, this algorithm guarantees every permutation is equally likely (uniform distribution) and runs in O(n) time. Iterating backward and swapping with a random earlier element eliminates the bias of naive shuffle methods.

📊 Why Fairness Matters

A naive sort-by-random gives non-uniform distribution — some orderings appear more often. Fisher-Yates eliminates this entirely. With 8 items there are 40,320 possible orderings, each with exactly 1/40,320 probability. Critical for games, experiments, and random sampling.
