Sheldon is very proud of his intelligence. To test his intelligence Howard designs a puzzle and asks him to solve it. The puzzle consists of special numbers which can be obtained by multiplying exactly two distinct prime numbers. Sheldon has to tell Howard what is the Kth element of this series. Help him.

For Example 6, 10, 14, 15 are the first few members of this series whereas 4, 9 and 12 are not.

Input

First line specifies T, the number of test cases.

Next T lines each gives 1 number, K

Output

Output 1 line for each test case giving the Kth element of this series.

Constraints

1 <= T <= 1000

1 <= K <= 2000000

Example

Input:
4
2
3
5
7

Output:
10
14
21
26

how to find bounds? hint please

nadstratosfer: 2018-06-30 11:44:35

Francky, your 0.00s here is such an eyesore ;) Can it be reproduced or is it a result of some server instability?

Started solving this in C just to downvote for all the frustration I've had trying to pass with Python several months back. Turned out the TL is not that bad: my best solution is 9x times faster than my first AC one. Spent some time cutting the fat off my program and enjoyed it. Apparently PyPy can get AC too! Thanks to the setter for not making it easy.

=(Francky)=> It's not instability, ;-)
At time I've solved it Python was not available, but now yes ! I'll try to find my old files... My C code is quite unreadable.

[NG]: It's wizardry then. Chapeau bas!

=(Francky)=> J'ai vu nombreux de tes jolis scores, j'en profite pour te féliciter également ;-)

simple_sieve <3

Please add Haskell.

Phew! Took 6 hours to get AC, after 3 TLEs.
Had to write a separate brute force program just to find the bounds.
Time limit is too strict. Had to several optimizations in sieve implementation.

i can't beliveve ac after so many tle :D :D:

OverFlow :)

anurag garg: 2014-01-06 20:56:51

took 3 hours to determine the bounds and 1 hour to remove Sigsegv error...finally AC
