FIBON - Fibonacci numbers

You are given number n and your task is to calculate nth Fibonacci number.


The first line of the standard input contains one integer t (t<101) which is number of test cases.

In each of the next t lines there is one number n (n<71).


For every test case print one number which is nth Fibonacci number.



Output: 55

My code is running perfectly in my editor and also in ideone but when i am submitting it, it is showing wrong answer. Can anybody tell me why?

There are 70 possible tests. Perhaps you check them all?

Can someone check why I have wrong answer? 13073804 Thanks

Also, is there a place where people are discussing tips/tricks? I noticed that on some problems I need newlines between answers and other times spaces. And I'm not sure what's really available on the remote system if I use bash (can I count on bc?) I tried to jump over to the forum but the Captcha seems broken.

Note that Fibonacci sequence asked for here starts with 1, that is, 1 1 2 and so on...

@Mitch - There was no \n at the end of the test. Sorry for that.

Is the input file badly formatted? I submitted two BF solutions, the first assuming "\n" newlines and the second assuming "\r\n", and both got TLE, while on my testing problem on Pyramid that same code got AC in 0.54s for an input file with t=100 and test cases (1, 2, ... , 69, 70, 70, ...). I do assume that the last line is terminated with a newline.

Edit: Whoops, my second submission is assuming "\n\r"... I'll rewrite that.

Edit 2: Still TLE...

@Piotr: Thanks! I guess omitting the last newline isn't really bad formatting, but it's usually right to assume that the newline is there, and of course matters a lot for BF. :)

@challenger/Piotr - kinda the wrong place to accept the praise, but yeah! I'm very pleased with BF_PRIME. I wanted to get below 140 as that's a better than 2:1 ratio code:output.
