SUMUP - Sum the Series |
Nilendu is a brilliant student of Mathematics and always scores A+ in it. His professor RamjiLal is quite impressed seeing his mathematical skills and asks him to sum the following series:
1/3 + 2/21 + 3/91 + 4/273 + .....
But the fact is Nilendu is quite lazy to do his assignment. He has to watch a film and many other activities to do. So he asks you for your help. Will you be able to solve it ??
Input
Input consists of t (number of test cases), then t line follows, each containing an integer N (1 <= N <= 10,000).
Output
A single line containing the sum upto Nth integer (rounded upto 5 digits)
Example
Input: 5Edit: The score is your source length. The smaller your code is, the more point you will get. All the solutions have been rejudged !!!

@Mostafa: I also prefer you to resubmit the 35-byte solution, but of course it's your choice. (Unless you have a reason for disqualifying other than what you mentioned, e.g. relying on broken test data.) Last edit: 2013-08-02 02:35:13 |

Actually , I only want the points :p so my 36-byte will be enough for now :) good job @ওয়াসী (Wasi) ;) (Edit): I've disqualified it , I don't want to be alone in the rank list :p any way, there is a 35-byte if some buddy reach it i'll resubmit my code . Last edit: 2013-08-01 09:33:41 |

oh man! after trying hard when i managed a 36B solution,now the best score is 35B! thank you Mostafa. Edit: Strange, 35 B solution vanished! Mostafa please keep your 35B solution buddy. Its a motivation for me. I will try harder to reach it No problem at all :) Last edit: 2013-08-01 09:10:37 |
