Nicola believes that Sophia calls to Home too much and her phone bill is much too expensive. He took the bills for Sophia's calls from the last few days and wants to calculate how much it costs.
The bill is represented as an array with information about the calls.
Help Nicola to calculate...
2014-01-01 01:12:13 181 2014-01-02 20:11:10 600 2014-01-03 01:12:13 6009 2014-01-03 12:13:55 200First day -- 181s≈4m -- 4 coins;
Second day -- 600s=10m -- 10 coins;
Third day -- 6009s≈101m + 200s≈4m -- 100 + 5 * 2 = 110 coins;
Total -- 124 coins.
Input: Information about calls as a tuple of strings.
Output: The total cost as an integer.
totalCost(["2014-01-01 01:12:13 181", "2014-01-02 20:11:10 600", "2014-01-03 01:12:13 6009", "2014-01-03 12:13:55 200"]) == 124
How it is used: This mission will teach you how to parse and analyse various types data. Sometimes you don't need the full data and should single out only important fragments.
0 < len(calls) ≤ 30
0 < call_duration ≤ 7200
The bill is sorted by datetime.
