Solution in C# (.NET Core 3.1.201) (judge verdict: Wrong Answer)

using System;
class Program
 {
   	static void Main(string[] args)
        {
    　　	string a = Console.ReadLine(); //標準入力
		string[] aa = a.Split(' ');
		

	       	int D = int.Parse(aa[0]);
	       	int T = int.Parse(aa[1]);
       		int S = int.Parse(aa[2]);

		
		bool test = false;

      double time = D/S;
      test = (double)T >=time;
		if(test){
			Console.WriteLine("{0}", "Yes");
		}else{
			Console.WriteLine("{0}", "No");
		}
		
    }
