The idea of a defer statement or a ScopeGuard has for a while been something I have wanted in c++ but up until recently I had always assumed that c++ did not have it. However, that's when I found std::experimental::scope_exit but it had a problem. Which was that it had not been implemented in any...

I would write the code this way: function getPayAmount() { if (isDead) return deadAmount(); else if (isSeparated) return separatedAmount(); else if (isRetired) return retiredAmount(); else return normalPayAmount(); } but a person with a different opinion insists the more proper way is: ...

I am new to coding/programming. About four months ago I decided to develop my skills using Python. After several books and a lot of assistance from this awesome community I developed the first part of my "Pizza Order System" program.

My target is to have an environment variable being set to a leading substring of $PWD and to be unset when $PWD does not start with that substring. So I decided to override cd like this (here I'm assuming the substring is just my home directory /home/enrico, but in general is fine for me that it ...

I am currently reviewing CTCI(Cracking the Coding Interview) The question is asking me to implement an algorithm which checks whether the characters in a string are all unique however they do not want me to use any auxillary data structures My Algorithm is relatively straight forward, I employ tw...

My exploration of Rust continues. I'm quite pleased with the 2-step table lookup for decoding variable bit-length codes here, for some reason I found this tricky to work out, but now it's done I like it. InputBitStream has a required "lifetime parameter", it seems these are not given meaningful n...

My implementation of a Sudoku solver. It isn't done using the most naive way but still it does an exhaustive search with some assistance from a heap. The only constraints I have used is the basic rules of Sudoku (a number can occur only once in a row, column and it's box). There probably are more...

Should I return true or country? Both work. Both return false and both return true if I remove the space from "Great Britain". Should this code be written differently altogether? var arr4Every = ["Great Britain", "Germany", "Italy", "France", "Portugal", "Albania"]; var results4Every = arr4Every...

Example 1: Input: "I0,Q4" Output: 2 Explanation: piece I is placed at 0, piece Q is placed at position 4. height of board is 2. Example 2 Input: "Q0,Q2,Q4,Q6,Q8" Output: 0 Explanation: 2 full rows get removed and height is zero There are not rotations ect for the scope of the problem. class Tetri...

I know the way I position the divs is not correct since...

I have a rails app with a Project model. Each project has usages which is numeric data. I need to get all the usage for each month and year.

I'm moving some files from a Linux machine to a Windows machine over a low-speed, possibly buggy experimental communications channel that I want to test. One of the tests is to transfer large numbers of large and small files and verify their cryptographic hashes at the receiving end. On the Lin...

I helped make a game for the Game Maker's Toolkit Game Jam a couple weekends ago and made an interface for the four different enemies, allowing the player to hit an enemy without worrying about what enemy they're hitting. The interface is as such: public interface IEnemyCombat { string Name()...

I am writing a python GUI application that plots weather data on a map for a specific region. It plots temperature, dewpoint, wind data, and icons that represent the sky conditions. It extracts the data for longitude/latitude from text files. I timed out how long it takes for the program to plot ...
