WebAnswer (1 of 6): It’s not hard to make a shuffling algorithm - just use Fisher-Yates. But yes, F-Y does have the built-in assumption of a source of random numbers, and if the numbers aren’t truly random then the algorithm’s guarantees of producing random shuffles aren’t guaranteed anymore. Gene... WebTime complexity is O(N log N), same as quick sort. Space complexity is O(N). This is not as efficient as a Fischer Yates shuffle but, in my opinion, the code is significantly shorter and more functional. If you have a large array you should certainly use Fischer Yates. If you have a small array with a few hundred items, you might do this.
