      return Math.Abs(dadYears-sonYears*2);
    }
  }
}​

答案5:

using System;

namespace Solution
{
  public class TwiceAsOldSolution
  {
    public static int TwiceAsOld(int dadYears, int sonYears)
    {
      // Add you code here.     
      return Math.Abs(dadYears - (sonYears * 2));
    }
  }
}​

答案6:

using System;
namespace Solution
{
  public class TwiceAsOldSolution
  {
    public static int TwiceAsOld(int dadYears, int sonYears)
    {
      // Add you code here.
      return Math.Abs(dadYears - sonYears * 2);
    }
  }
}​

答案7:

using System;

{
  public class TwiceAsOldSolution
  {
      public static int TwiceAsOld(int dadYears, int sonYears) => Math.Abs(2 * sonYears - dadYears);
  }
}​

答案10:

using System;
namespace Solution
{
  public class TwiceAsOldSolution
  {
    public static int TwiceAsOld(int dadYears, int sonYears)=>Math.Abs((2*sonYears)-dadYears);
  }
}​

答案11:

  {
    public static int TwiceAsOld(int dadYears, int sonYears)
    {
      int yearCalc = 0;
      
      yearCalc = (dadYears - 2*sonYears);
      
      if(yearCalc < 0)
        {
        yearCalc = yearCalc * -1;
        }
      
      return yearCalc;
              
      // Add you code here.
    }
  }
}​

  public class TwiceAsOldSolution
  {
    public static int TwiceAsOld(int f, int s)
    {
      
            return (f > s * 2)?  f - s * 2:  s * 2 - f;
            return f;
    }
  }
}​

答案13:

namespace Solution
{
  public class TwiceAsOldSolution
  {

    {
    int doubleSon = (sonYears*2);
      
      if (dadYears > (sonYears*2))
      {
      
      int yearsAgo = dadYears - doubleSon;
      return yearsAgo;
      }
      else 
      {
       int yearsLeft = doubleSon - dadYears;
       return yearsLeft;
      }
      
    }
  }
}​

答案14:

namespace Solution
{
  public class TwiceAsOldSolution
  {
    public static int TwiceAsOld(int dadYears, int sonYears) => 
    
    (dadYears - sonYears*2)>0 ? (dadYears - sonYears*2) : -(dadYears-sonYears*2);

  }
}​

答案15:
