Some times programming contest can be boring if you get stuck on a problem for a long period of time but don’t get AC. But you won’t get bored if you can witness a magic trick right now in the middle of the contest and an AC as a bonus.

To get an AC, you’ll have to follow a bunch of instructions. If you can follow the instructions properly, it is guaranteed that you’ll get an AC. The instructions are as follows.

1. Think of any non-negative integer number.
2. Subtract 1 from the number you have thought of.
3. Multiply the number you have now by 3.
4. Add 12 to the number.
5. Divide the number by 3.
6. Add 5 to the number.
7. Subtract the original number you thought at first from the number you have now.
8. Double the number you have now.
9. Add 6 to the number.
10. Divide that number by 2.
11. Now subtract the number you had after executing step 7.
12. Print the number you have now.
