Problem Statement

Takahashi is a member of a programming competition site, ButCoder.

Each member of ButCoder is assigned two values: Inner Rating and Displayed Rating.

The Displayed Rating of a member is equal to their Inner Rating if the member has participated in 10 or more contests. Otherwise, the Displayed Rating will be their Inner Rating minus 100 \times (10 - K) when the member has participated in K contests.

Takahashi has participated in N contests, and his Displayed Rating is R. Find his Inner Rating.

Constraints

All values in input are integers.

1 \leq N \leq 100

0 \leq R \leq 4111

Input

Input is given from Standard Input in the following format:

N R

Output

Print his Inner Rating.

Sample Input 1

2 2919

Sample Output 1

3719

Takahashi has participated in 2 contests, which is less than 10, so his Displayed Rating is his Inner Rating minus 100 \times (10 - 2) = 800.

Thus, Takahashi's Inner Rating is 2919 + 800 = 3719.

Sample Input 2

22 3051

Sample Output 2

3051

Solution in Rust (1.15.1) (judge verdict: Accepted)

use std::io;
fn main() {
    let line = read_line();
    let mut split = line.split(' ').map(|s| s.parse::<usize>().unwrap());
    let count = split.next().unwrap();
    let disp_rate = split.next().unwrap();
    let internal_rate = if count >= 10 {
        disp_rate
    } else {
        disp_rate + 100 * (10 - count)
    };
    println!("{}", internal_rate);
}
fn read_line() -> String {
    let mut line = String::new();
    io::stdin().read_line(&mut line).unwrap();
    line.pop();
    line
}
