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 Python (3.4.3) (judge verdict: Runtime Error)

n, a, b = map(int, input().split())

from math import factorial
ans = 0

if n % 2 == 1:
    for i in range(1, n // 2 + 1):
        ans += factorial(n) // factorial(i) // factorial(n - i)
    ans *= 2 + 1
else:
    for i in range(1, n // 2):
        ans += factorial(n) // factorial(i) // factorial(n - i)
    ans *= 2
    ans += factorial(n) // factorial(n // 2) // factorial(n - n // 2) + 1

ans -= factorial(n) // factorial(a) // factorial(n - a)
ans -= factorial(n) // factorial(b) // factorial(n - b)
print(ans)
