C :

#include<stdio.h>

void main () {
	int n;
	scanf("%d",&n);
	
	if(n%30==0){
		printf("%d",n/30);
	}else{
		printf("%d",n/30+1);
	}
}

C++ :

#include <bits/stdc++.h>
using namespace std;

int main(){
    int n;
    cin>>n;
	if(n % 30 == 0){
		cout<<n / 30;
	}else{
		cout<<n / 30 + 1;
	}
}
 

Java :

import java.util.Scanner;
public class Main
{
	public static void main(String[] Args)
	{
		Scanner sc = new Scanner(System.in);
		int a = sc.nextInt();
		int n;
		if(a%30 == 0)
			n = a/30;
		else
			n = a/30+1;
		System.out.println(n);

	}
}

Python :

n = int(input())
if n % 30 == 0:
    s = n // 30
    print(s)
else:
    s = n // 30 + 1
    print(s)
