WebCorrectness Proof for Fisher-Yates Shu e Peter J. Haas February 25, 2024 We can assume without loss of generality that we start out with array x = [1;2;:::;N]. Now consider an arbitrary permutation x0= [b 1;b 2;:::;b N] where b 1;:::;b N are distinct integers between 1 and n. What is the probability that the F-Y algorithm produces x0 from x?
