comment Number of binary numbers given constraints on consecutive elements
@DanielFischer unfortunately you have to register there to be able to see a list of problems. The problem there was absolutely the same as posted here (even the example with 1, 1, 2, 1). Right now the competition finished, and everyone can see the solutions, so this guy is surely no longer interested in the solution :-).

comment Number of binary numbers given constraints on consecutive elements
Ongoing competition: hackerrank.com/contests/worldcodesprint/challenges/… Such a coincidence that your professor gave this problem just during the competition :-). Has he gave any other questions from the competition?

comment No. of ways to Generate the String
do not forget to add that you want to cheat in a programming competition and that in a couple of hours the solution will be visible to everyone. So you basically force other people to solve it for you to collect points you do not deserve

comment Is there any mathematic meaning of generating function at some value?
@BrevanEllefsen sorry, that 1.5 was from old question, when I incorrectly calculated the radius.

comment Is there any mathematic meaning of generating function at some value?
@BrevanEllefsen thank you for spotting a mistake. My interpretation of fibonacci sequence is $f_n = f_{n-1} + f_{n-2)$ but it would be nice to hear the answer for both cases.

comment probability that a string of length $m$ over the alphabet of length $n$ will have exactly $k$ as the number of most frequent elements
@dREaM thank you for a reply. It kind of makes sense to me that you take $a$ from generating functions, but it is unclear to me why do you divided by combinations with replacements and not by $n^m$. Also is there a hope to get an easier formula?

comment How to interpret negative probability for a strategy in mixed nash equilibrium?
@Shane I am really sorry. I was speaking about zero-sum games. I should have been more clear.

comment Closed form or approximation of $\sum\limits_{i=0}^{n-1}\sum\limits_{j=i + 1}^{n-1} \frac{i + j + 2}{(i + 1)(j+1)} (i + 2x)(j +2x)$
wow, this is just amazing. Thank you
