So it was Sunday late evening and I’m, almost sleeping, randomly cruising through reddit, came to this article. In which author shares his experience of becoming “better programmer”, and I found it some what controversial for me. Generally he takes two common programming problems and compares how he did them in the start of his programming career and now. This is cool short reading itself and 100% educational, but in my opinion for another reason than author thought. ... Read more

Right of the way gonna say that doing it on Saturday just because didn’t feel like doing it at all. This task is based on Mondays one and consists of two parts. Task is here, latest solution is here. So with regular task I came pretty quickly and there is really nothing special comparing with easy one. (def wire-rules {:s0 {\w :s1, \r :s2} :s1 {\w :s2, \o :s3} :s2 {\b :s3, \r :s0} :s3 {\b :s3, \o :s4, \g :s5} :s4 {\g :exit} :s5 {\o :exit}}) (defn end? ... Read more

Another easy Monday except this one is little bit more easy than last one. Here is the task. I finished rather fast with initial version, but doing little changes for of times I’ve ended up with this. (ns daily-programmer.20161121_easy.core (:use [clojure.string :only [split-lines]])) (def wire-rules-m {"white" {:to-cut #{} :not-to-cut #{"white" "black"}} "red" {:to-cut #{"green"} :not-to-cut #{}} "black" {:to-cut #{} :not-to-cut #{"white" "green" "orange"}} "orange" {:to-cut #{"red" "black"} :not-to-cut #{}} "green" {:to-cut #{"orange" "white"} :not-to-cut #{}} "purple" {:to-cut #{} :not-to-cut #{"purple" "green" "orange" "white"}}}) (defn can-cut? ...

So I just randomly (from /r/coding actually) came across this site which is built over idea of mocking interviews similar to big IT companies do. And it got my attention because it has some examples of programming tasks in its blog. Tasks, which I found seem to be not hard at all (authors mention this as well) and I think that such problems may be asked either for lower grade positions or during initial stages of interviewing process. ...

Since this is first post on daily-programmer topic I need some introduction. So there is this awesome sub reddit called DailyProgrammer where programming tasks on algorithms are posted 3 times a week. Easy ones on Mondays, intermedium ones on Tuesdays and hard ones on Friday. You can post Your solutions in favorite language and compile and test them directly in the comment section with /u/CompileBot. I’ve been aware about this thing for already quite some time but never was able to stick with it for too long. ... Read more
