fast.Let's look at the last example. The algorithm g is 2n2, the algorithm h is 3n + 1, the algorithm i is 2n2 + 3n + 1 (as shown in table 2-8-4). This set of data should be seen very clearly. When the value of n is getting bigger, you will find that 3n+1 has not been able to compare with the results of 2n2, and it is almost negligible in the end. In other words, as the n value becomes very large, the algorithm G is already approaching algorithm I.
