Working Hours

Write a program that helps you calculate the employees’ time spent on work.

The input contains several test cases. Each line of a test case gives the length of a time period spent on work in H.MM format, where H denotes the number of hours (H ≥ 0), and MM denotes the minutes, the latter always given with two digits (0 ≤ HH < 60).

Test cases are terminated by a line containing the string „END”. You may assume that all employees spend at least a short time on work.

The program should write to the standard output the total time spent on work by each employee, in the same format as in the input.

Sample Input

1. 3.20
2. 4.30
3. 5.00
4. END
5. 10.00
6. END

Output for Sample Input

1. 12.50
2. 10.00

Possible solutions: main1.c and main2.c.
