AMR11E - Distinct Primes


Arithmancy is Draco Malfoy's favorite subject, but what spoils it for him is that Hermione Granger is in his class, and she is better than him at it. Prime numbers are of mystical importance in Arithmancy, and Lucky Numbers even more so. Lucky Numbers are those positive integers that have at least three distinct prime factors; 30 and 42 are the first two. Malfoy's teacher has given them a positive integer n, and has asked them to find the n-th lucky number. Malfoy would like to beat Hermione at this exercise, so although he is an evil git, please help him, just this once. After all, the know-it-all Hermione does need a lesson.

Input

The first line contains the number of test cases T. Each of the next T lines contains one integer n.

Output

Output T lines, containing the corresponding lucky number for that test case.

Constraints

1 <= T <= 20
1 <= n <= 1000

Example

Sample Input:
2
1
2

Sample Output:
30
42

Easy one !! Sieve() Pre() O(1) 0.00 :)

simple bruite force..nothing else..:P

AC in one go :)

sieve .... easy problem AC in one go

And with this problem completed my half century on SPOJ....:P

I just added primes up to 500 in an array , used a loop and checked if the number is divided by at least 3 primes . It took 1 full day for me.

easier1.........use sieve.

for who's answer for n = 1000 is 2988,there is at least three distinct prime factors,it is mean equal or bigger than three

Got it. :-) I was calculating for 3 distinct prime factors only i.e. not for number of distinct prime factors greater than 3.

Simple Brute Force and, used cin and cout. AC in 0.00 :P
