Bob loves travelling by plane. Thankfully, his job of being a businessman involves traveling a couple of times during the month. Bob is a busy man. He has months when he uses his private jet in order to go and sign new contracts. In a contract month, he travels 3 times per week. Although Bob loves his work, he also cares about his family. He spends family months, when he has 1 less travel per week than a contract month and he travels only 2 weeks. The other months are considered "normal" during which Bob travels 2/5 less than during contract months.

In addition, if the year is leap, Bob travels 5% more overall. Assume that a month has exactly 4 weeks.

Your task is to write a program that calculates how many times Bob travels around the world during the year (rounded down to the nearest integer number).

### Input

The input data should be read from the console. It consists of three input values, each at separate line:

• The string "leap" for leap year or "normal" for year that is not leap.
• The number c – number of months Bob signs contracts in the year.
• The number f – number of months that Bob spends with his family.

The input data will always be valid and in the format described. There is no need to check it explicitly.

### Output

The output data must be printed on the console.

• On the only output line you must print the number of travels as integer.

### Constraints

• The numbers c is in range [0...12] and f is in range [0…12].
• Allowed working time for your program: 0.25 seconds.
• Allowed memory: 16 MB.

### Examples:

Interesting C# task :-) A bit foggy in the description (need to be careful with weeks, months and years - not to mention - the family time), but otherwise cool :-)

Here is my solution:

```using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

class TravellerBob
{
static void Main()
{
decimal contractsMonths = decimal.Parse(Console.ReadLine());//per month = 12
decimal familyMonths = decimal.Parse(Console.ReadLine());//per month = 4

decimal contractFlights = contractsMonths * 12;
decimal familyFlights = familyMonths * 4;
decimal normalFlights = ((12 - (contractsMonths + familyMonths)) * 12) * 0.6m;//0.6 - because 3/5 = 0.6 (5/5-2/5=3/5)

decimal yearLeapFlights = (contractFlights + familyFlights + normalFlights) + ((contractFlights + familyFlights + normalFlights) * 0.05m);
decimal yearNormalFlights = contractFlights + familyFlights + normalFlights;

switch (yearType)
{
case "leap":
Console.WriteLine(Math.Floor(yearLeapFlights));
break;
case "normal":
Console.WriteLine(Math.Floor(yearNormalFlights));
break;
}
}
}```
