Problem Statement

In "Takahashi-ya", a ramen restaurant, a bowl of ramen costs $700$ yen (the currency of Japan), plus $100$ yen for each kind of topping (boiled egg, sliced pork, green onions).

A customer ordered a bowl of ramen and told which toppings to put on his ramen to a clerk. The clerk took a memo of the order as a string $S$. $S$ is three characters long, and if the first character in $S$ is o, it means the ramen should be topped with boiled egg; if that character is x, it means the ramen should not be topped with boiled egg. Similarly, the second and third characters in $S$ mean the presence or absence of sliced pork and green onions on top of the ramen.

Write a program that, when $S$ is given, prints the price of the corresponding bowl of ramen.

Constraints

• $S$ is a string of length $3$.
• Each character in $S$ is o or x.
