No it was not accepted but it passed the pretests.

Check for loop carefully There is no index i inside the loop.

Even this passed the pretests,very weak test cases.

int main()
{

	long long int l,x,r,y,k;
	cin>>l>>r>>x>>y>>k;
	int flag=0;
	for(int i=x;i<=y;i++)
	{
		if(l<=x*k&&x*k<=r) //this line though :)
			{flag=1;break;}
	}
	if(flag)
		cout<<"YES\n";
	else
		cout<<"NO\n";
	
}
