Question

我有一个List<int[]>，我是通过将整数数组分成4组来填充的。现在，我需要获取数组中两个最高数字的差。我尝试了Array.Sort，但是在继续操作方面却遇到了麻烦。

到目前为止我做了什么？

    public static void solution(int[] T)
    {
        List<int[]> splitted = new List<int[]>();//This list will contain all the splitted arrays.
        int lengthToSplit = T.Length / 4;

        int arrayLength = T.Length;

        for (int i = 0; i < arrayLength; i = i + lengthToSplit)
        {
            int[] val = new int[lengthToSplit];

            if (arrayLength < i + lengthToSplit)
            {
                lengthToSplit = arrayLength - i;
            }
            Array.Copy(T, i, val, 0, lengthToSplit);
            splitted.Add(val);
        }

        //this is the part where I must get the difference between the two highest numbers in an integer array and put into another list.

  foreach (int[] integerarray in splitted)
    {
      //get the difference of the two highest numbers per integer array and place it on another List<int>
    }

    }

Answer 1

获取整数数组中两个最高数字之间的差并放入另一个列表

您可以使用LINQ和Math.Abs：

List<int> differenceList = splitted
  .Select(list => list.OrderByDescending(i => i).Take(2).ToArray())
  .Select(highestTwo => Math.Abs(highestTwo[0] - highestTwo[1]))
  .ToList();

整数数组获取两个最高数字之间的差
