include<bits/stdc++.h>

using namespace std;

typedef long long int ll;

int isprime(ll n)

{

if(n<=3)

    return 1;

if(n%2==0||n%3==0)

    return 0;

for(ll i=5;i*i<=n;i+=6)

{

    if(n%i==0||n%(i+2)==0)

        return 0;

}

return 1;

}

int main()

{

//ios_base::sync_with_stdio(0);cin.tie(NULL);cout.tie(NULL);

ll N,i;

cout<<"\nEnter the Number N :";cin>>N;

cout<<"\nPrime Numbers <="<<N<<" are : \n";

for(i=2;i<=N;i++)

{

    if(isprime(i))

            {
