C :

#include<stdio.h>
int main()
{
	int t,H;
	scanf("%d",&t);
	while(t--)
	{
		int n=0;
		scanf("%d",&H);
		do
		{
			H-=10;
			if(H>0)
				H+=5;
			n++;
		}while(H>0);
		printf("%d\n",n);
	}
}

Java :

import java.util.Scanner;
public class Main
{
	public static void main(String[] args)
	{
		Scanner sc=new Scanner(System.in);
		int t=sc.nextInt();
		for(int i=1;i<=t;i++){
			int H=sc.nextInt();
			int m=H%10;
			if(H<=10){
				System.out.println(1);
			}else if(H%5==0){
				System.out.println(H/5-1);
			}else{
				System.out.println(H/5);
			}
		}
	}
}
