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 !!!

210 in C. It helps if you filter \n and \t from the code (except for the beginning \n and the one printing). |
