The regular formula for the pancake problem is total time equal to the number of pancakes multiplied by 2 divided by the number of pans available per pan multiplied by the time to cook each side. The first time you put the front of 1 and the front of 2, the second time you put the back of 1 and the front of 3, and the third time you put the back of 2 and the back of 3. This way a **** takes 3 times 3 equals 9 minutes to fry a great time saver.

Regular characteristics of the pancake problem

The first time we will be two pancakes at the same time into the 1 minute, the first pancake from the front turned into the back of the second pancake out, into the front of the third pancake, the end of the second minute when the first pancake has been cooked, take out and put in the second pancake to cook the second pancake on the back of the pancake at the same time! Cook the back of the 3rd pancake so that at the end of the 3rd minute both the 2nd and 3rd pancake are cooked.

Can be taken out of the pot together, this time the time spent only 3 minutes if an even number of sheets who branded are the same, there is no skill to speak of step by step time is fixed, then the pancake problem is only greater than or equal to the state of the odd number of sheets of pancakes can be counted as a valid question, for example, branding 9, is the equivalent of the front of the branding of the 6 sheet this is unchanged, the only difference is that the back of the branding of the 3 sheet time savings.
