Topic 1133: Points of Merit (C++/java)

Title Description:

Peking University performed an average credit score point system (GPA) for undergraduates. The students ' actual scores will be calculated according to the different credits of different disciplines.
The formula is as follows:
Actual performance points
90--100 4.0
85--89 3.7
82--84 3.3
78--81 3.0
75--77 2.7
72--74 2.3
68--71 2.0
64--67 1.5
60--63 1.0
60 or less 0
1. The grade point of a course = the performance point * the course credit
2. Points of achievement = sum of all academic points and/or all course credits
You are asked to write a program to find out the rating points (GPA) for someone a.

Input:

Number of total courses in the first line n (n<10);
The second line of the corresponding course credit (two credits separated by a space);
The third line corresponds to the actual score of the course;
All the numbers entered here are integers.

Output:

Output has a row, the performance points, accurate to the decimal point after 2 decimal places. (printf ("%.2f", GPA);)

Sample input:

54 3 4 2 391 88 72 69 56

Sample output:

2.52
