常時遍有

I come up with a special test case is  < countdown = 1 , and the input is 1 1 1 1 1 1 > should got the answer 6,

my original answer didn't mathc this case and I didn't inspire this case in the competition,

and can't see the blind point in competition, so finally nothin more to do with the wrong answer and wait till the end of comp.

2 weeks later I compare with other's pass answer, and meditation with my expereience, finally fix a small error and got the correct answer as below:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace GoogleKickStart.Problem
{
	class Countdown
	{

		public  static void Run()
		{


			List<int> nums = new List<int>();
			List<string> info = new List<string>();

			int caseCou = Convert.ToInt32(Console.ReadLine());



			for (int i = 0; i < caseCou; i++)
			{
				int totalCountDown = 0;

				info = Console.ReadLine().Split(' ').ToList();
				int countdown = Convert.ToInt32(info[1]);
				nums = Console.ReadLine().Split(' ').Select(s => Convert.ToInt32(s)).ToList();

				int accumulateCuontdown = 0;
				for (int j = 0; j <= nums.Count - countdown; j++)
				{
					if (nums[j] == countdown)
					{
						bool isCd = true;
						//int jump = -1;
						for (int k = 0; k < countdown; k++)
						{
							if (nums[j + k] == countdown - k)
							{
								//jump++;
							}
							else
							{
								isCd = false;
								break;
							}
						}

						if (isCd)
						{
							totalCountDown++;
						}
						//if(jump > 0)
						//	j += jump;

					}


				}

				Console.WriteLine($"Case #{i + 1}: {totalCountDown}");

				
			}



		}

	}
