Constantly getting wrong answer as output.Why?

I have developed the following code for this problem.It runs perfectly on my system and I have developed it to exactly match the output required.But why its still giving wrong answer.

import java.io.*;

class a
{
	public static void main(String args[])
	{
		int num,count=0,add=0,temp,n;

		BufferedReader br=null;
		try
		{
			br=new BufferedReader(new InputStreamReader(System.in));
			n=Integer.parseInt(br.readLine());
			while(n-->0)
			{
				num=Integer.parseInt(br.readLine());
				if(num>=1&&num<=1000000000)
				{
					if(num>=5)
						{
							while(num>5)
								{
									temp=num/5;
									add+=temp;
									num=temp;
								}
						}
					else
						add=0;
					System.out.println(add);
					add=0;
				}
			}
			
		}catch(Exception e)
		{
			// do nothing;
		}
	}
}

I am pretty sure changing the line “while(num>5)” to “while(num “>=” 5)” will work. you should include 5 also
