                                          Uncowed Forces

Kevin Sun has just finished competing in Codeforces Round #334! The round was 120 minutes long and featured five problems with maximum point values of 500, 1000, 1500, 2000, and 2500, respectively. Despite the challenging tasks, Kevin was uncowed and bulldozed through all of them, distinguishing himself from the herd as the best cowmputer scientist in all of Bovinia. Kevin knows his submission time for each problem, the number of wrong submissions that he made on each problem, and his total numbers of successful and unsuccessful hacks. Because Codeforces scoring is complicated, Kevin wants you to write a program to compute his final score.

Codeforces scores are computed as follows: If the maximum point value of a problem isx, and Kevin submitted correctly at minutem but made w wrong submissions, then his score on that problem is. His total score is equal to the sum of his scores for each problem. In addition, Kevin's total score gets increased by 100 points for each successful hack, but gets decreased by50 points for each unsuccessful hack.

All arithmetic operations are performed with absolute precision and no rounding. It is guaranteed that Kevin's final score is an integer.

Input

The first line of the input contains five space-separated integers m₁, m₂,m₃, m₄, m₅, wherem_i (0 ≤ m_i ≤ 119) is the time of Kevin's last submission for problemi. His last submission is always correct and gets accepted.

The second line contains five space-separated integers w₁, w₂,w₃, w₄, w₅, wherew_i (0 ≤ w_i ≤ 10) is Kevin's number of wrong submissions on problemi.

The last line contains two space-separated integers h_s andh_u (0 ≤ h_s, h_u ≤ 20), denoting the Kevin's numbers of successful and unsuccessful hacks, respectively.

Output

Print a single integer, the value of Kevin's final score.

Example

Input

20 40 60 80 1000 1 2 3 41 0

Output

4900

Input

119 119 119 119 1190 0 0 0 010 0

Output

4930

Note

In the second sample, Kevin takes 119 minutes on all of the problems. Therefore, he gets of the points on each problem. So his score from solving problems is . Adding in10·100 = 1000 points from hacks, his total score becomes3930 + 1000 = 4930.

题解：这题看上去很可怕，只是因为看不懂英语，其实很简单，就是直接带公式计算而已

下面是我的代码：

#include<cstdio>#include<algorithm>#include<cstring>#include<cmath>#include<cstdlib>#include<iostream>using namespace std;int main(){double m1, m2, m3, m4,m5,w1, w2, w3, w4, w5,hu,hs,max1,max2,max3,max4,max5;while(scanf("%lf%lf%lf%lf%lf",&m1,&m2,&m3,&m4,&m5)!=EOF){double p1,p2,p3,p4,p5,endd;;    scanf("%lf%lf%lf%lf%lf",&w1,&w2,&w3,&w4,&w5);scanf("%lf%lf",&hu,&hs);p1=(1-m1/250)*500-50*w1;p2=(1-m2/250)*1000-50*w2;p3=(1-m3/250)*1500-50*w3;p4=(1-m4/250)*2000-50*w4;p5=(1-m5/250)*2500-50*w5;max1=max((0.3*500),p1);max2=max((0.3*1000),p2);max3=max((0.3*1500),p3);max4=max((0.3*2000),p4);max5=max((0.3*2500),p5);hu=hu*100;hs=hs*(-50);endd=max1+max2+max3+max4+max5+hu+hs;printf("%.0lf\n",endd);}return 0;}
