Gondwanaland Telecom makes charges for calls according to distance and time
of day. The basis of the charging is contained in the following schedule, where
the charging step is related to the distance:
Charging Step |
Day Rate 8am to 6pm |
Evening Rate 6pm to 10pm |
Night Rate 10pm to 8am |
A B C D E |
0.10 0.25 0.53 0.87 1.44 |
0.06 0.15 0.33 0.47 0.80 |
0.02 0.05 0.13 0.17 0.30 |
All charges are in dollars per minute of the call. Calls which straddle a rate
boundary are charged according to the time spent in each section. Thus a call
starting at 5:58 pm and terminating at 6:04 pm will be charged for 2 minutes
at the day rate and for 4 minutes at the evening rate. Calls less than a minute
are not recorded and no call may last more than 24 hours. Write a program that
reads call details and calculates the corresponding charges.
Input lines will consist of the charging step (upper case letter 'A'..'E'),
the number called (a string of 7 digits and a hyphen in the approved format)
and the start and end times of the call, all separated by exactly one blank.
Times are recorded as hours and minutes in the 24 hour clock, separated by one
blank and with two digits for each number. Input will be terminated by a line
consisting of a single #.
Output will consist of the called number, the time
in minutes the call spent in each of the charge categories, the charging step
and the total cost in the format shown below.
