Fisher yates shuffle complexity

Web1 You need to understand that OrderBy returns an ordered collection - it doesn't sort in-place. I'd also argue that Jeff is just shifting from one source of pseudo-randomness to another - using a modified Fisher-Yates shuffle with a decent source of randomness is neater than using OrderBy, IMO. – Jon Skeet Oct 5, 2013 at 19:00 Code Added.
