Practice shows that after saving the world one needs to eat a piece of halvah made according to a classical recipe.

Grate sunflower seeds and toast them on a frying pen. Fry flour on a dry skillet, stirring thoroughly until the flour gains a cream color. Then, mix flour and grated seeds well, and grate them together once more. Add oil and mix.

Mix water and sugar in a saucepan and bring to boil. Boil until the sugar dissolves, then pour this syrup over the flour-seeds mix, and mix well until an even consistency is reached. Place in a refrigerator until the halvah turns hard.

In the end you will get 700 grams of halvah.

Calculate how many grams of halvah you will get out of n cups of seeds, if you have infinite amount of other ingredients.

Input contains one integer n — number of cups of seeds that you have (1 ≤ n ≤ 10).

Output one integer — amount of halvah in grams. It is guaranteed that the answer will be an integer.
