無聊寫一個氣泡排序

        public static int[] mpSort(int[] arrayInt)
        {
            if (arrayInt.Length < 2)
            {
                return arrayInt;
            }
            for (int i = 0; i < arrayInt.Length - 1; i++)
            {
                for (var j = i + 1; j < arrayInt.Length; j++)
                {
                    if (arrayInt[i] > arrayInt[j])
                    {
                        int value = arrayInt[i];
                        arrayInt[i] = arrayInt[j];
                        arrayInt[j] = value;
                    }
                }
            }
            return arrayInt;
        }
