namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            int t = int.Parse(Console.ReadLine());
            for (int i = 0; i < t; i++)
            {
                int k = int.Parse(Console.ReadLine());
                int n = int.Parse(Console.ReadLine());
                int[] room = new int[(k + 1) * n];
                
                for (int j = 1; j <= n; j++)
                {
                    room[j] = j;
                }
                for (int r = 1; r <= k; r++)
                {
                    for (int l = 1; l < n; l++ )
                    {
                        room[l + 1] = room[l] + room[l + 1];
                    }
                }
                Console.WriteLine(n == 1 ? 1 : room[n]);

            }

        }
