                  // 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).

                  // (2nlogn-logn*logn+logn)/2 = nlog(n) - log(n*n) + log(n) = nlog(n) + log(n/n*n)
