C :

#include<stdio.h>   

int main(){ 
	int n,i,c=0;
	scanf("%d",&n);
	
	
	for(i = 1;i <= n;i++){
		if( i % 3 == 2 && i % 5 == 3 && i % 7 == 2){
			c++;
		}
	}
	
	printf("%d",c);
	return 0;
} 

C++ :

#include <iostream>
using namespace std;
int main(){
	int n,i,a;
	a=0;
	cin>>n;
	for(i=1;i<=n;i++){
		if(i%3==2&&i%5==3&&i%7==2){
		a++;	
		}
		
	}
	cout<<a<<endl;
}

Pascal :

var
        i,n,m:integer;
begin
        read(n);
        for i:=1 to n do
                if (i mod 3=2) and (i mod 5=3) and (i mod 7=2) then m:=m+1;
        write(m);
end.

Java :

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		@SuppressWarnings("resource")
		Scanner scanner=new Scanner(System.in);
		int m=scanner.nextInt();
        int c=0;
			for (int a=1;a<=m;a++)
				if (a%3==2&&a%5==3&&a%7==2)
					c++;
			System.out.println(c);
		}	
	}

Python :

i=1
s=0
n=int(input())
while i<=n:
  a=i//1000
  b=i//100%10
  c=i//10%10
  d=i%10
  if i%3==2 and i%5==3 and i%7==2:
    s+=1
  i+=1
print(s)
