Array Shuffle

Array Shuffle Array shuffle rearranges elements into a random order such that every permutation is equally likely. You use it when unbiased randomization is required, such as sampling, randomized algorithms, or testing. Problem Given an array $A$ of length $n$, produce a permutation where each of the $n!$ possible orderings occurs with equal probability. Algorithm Use the Fisher–Yates shuffle. Iterate from the end and swap each position with a random...
