[Codewars #4] Keep Hydrated! (8kyu)

Instructions

Nathan loves cycling.

Because Nathan knows it is important to stay hydrated, he drinks 0.5 litres of water per hour of cycling.

You get given the time in hours and you need to return the number of litres Nathan will drink, rounded to the smallest value.

For example:

time = 3 ----> litres = 1

time = 6.7---> litres = 3

time = 11.8--> litres = 5

My Solution

using System;

public class Kata
{
  public static int Litres(double time)
  {
    int intTime = (int)time;

    //The fun begins here.
    return (intTime / 2);
  }
}

어렵지 않게 해결.

Best Practices

using System;

public class Kata
{
  public static int Litres(double time)
  {
    return (int)(time/2);
  }
}

내 해결 방법과 유사하다.

Best Practices 2

using System;

public class Kata
{
  public static int Litres(double time) => (int)(time*0.5);

}

2번째로 좋은 Best Practices인데..
