Web3. I was comparing the original Fisher-Yates shuffle vs the modern Fisher-Yates shuffle. This reduces the algorithm's time complexity to O (n), compared to O (n 2) for the naive implementation. Ok I cannot understand how is it that we have n 2 for the original algorithm. You see, our first trip is to write out the random numbers.
