How this machine operates:
1.The first 2 earths are converted to salt
2.The next 2 earths are deposited for later
3.Then, the 5th earth shall be attached by 6th earth
4.Move the obstacles so one of the attached earths can become salt
5.Position the attached salt in the input's position (where the earth is generated)
6.Move the obstacles again and then push the earth-salt element upwards, attaching the salt to the 7th earth
7.Proceed with attaching the rest of the salt and earth atoms accordingly. The product has been created successfully.
8.return to the initial position
