    n = int(input())
    k = 0
    k += (((n//2)-2)//3)*3 + (((n//2)-2) - ((n//2)-2)//3) + 4 + (n//2 - n//6)*3 + (n//6)*5 
    if n%2 != 0 :
        if n%3 == 0:
            k+= 3
        else: k+=1 
    print(k)

	scanf("%lld",&n);
	printf("%lld\n",n+(n/2+n/3)*2);
	return ;
}
signed main() {
	int T;
	scanf("%lld",&T);
	while(T--) solve();
