                  // for case b (just grab the m first items) or in linear time for case a (find the
                  // beginning of items
                  // with correct enchantment, index x, and take all items from x to x+m).
                  // Basically, whenever m > log(n) we have: m*(2n-m+1)/2 = (2nm-m*m+m)/2 >
                  // (2nlogn-logn*logn+logn)/2 = nlog(n) - log(n*n) + log(n) = nlog(n) + log(n/n*n)
                  // =
                  // nlog(n) + log(1/n) = nlog(n) - log(n) = (n-1)log(n)
                  // So for m < log(n) then m*(2n-m+1)/2 > (n-1)log(n) and m*(2n-m+1)/2 > nlog(n)
