[Solved] Javascript Regex Conditional

Here’s a solution which uses non-capturing groups (?:stuff) which I prefer so I don’t have to dig through the result groups to find the string I’m interested in. (?:#)(?:[\w\d]+-)?([\w\d]+) First it throws out the # character, then throws out the stuff up to and including the – character, if it is there, then groups the … Read more

[Solved] In C#, String .Replace wont replace danish chars

Most Unicode characters have multiple versions that can look very alike. For example: 1????1①⑴ var s = “æӕ”.Replace(“æ”, “ae”); // s = “aeæ” var v = “æӕ”.Select(c => (int)c).ToArray(); // { 230, 1237 } I consider it a good practice to expect the unexpected (especially when it comes to user input) var s = “æӕ”; … Read more

[Solved] SIGABRT called when calling find() on a string element in an array [closed]

It’s pretty simple why it’s crashing when you change that line. In the version that crashes you check whether words[j].find(new_word) is equal to std::string::npos and then call s.erase(s.find(new_word), …). Of course, s.find(new_word) could still be std::string::npos, and string::erase throws an exception when the first argument is out of range. In the version that you say … Read more

[Solved] Berkeley DB C++ showing incorrect key-value string data

Solution was to change datatype of key values from constant character pointer const char * to char array. char fruit[sizeof(“fruit”)] = “fruit”; char apple[sizeof(“apple”)] = “apple”; Additionally , even using string instead of const char * for key-values gives similar issue as mentioned in the question, somehow I could make it work only with char … Read more

[Solved] Why is this programming style not used? [closed]

I think this style is not used, because the best practice is to split up code into small functions/classes/methods anyway. This way, the variable count in each scope is reduced without using scoping blocks. Unlike other languages, like Rust, where scoping has immediate consequences on memory allocation, I don’t see a huge benefit in JavaScript … Read more

[Solved] how can I square the numbers between 0 and any input with extremely large numbers in python [closed]

If I am interpreting your question correctly, you simply need to devise a very simple list comprehension program. Getting the square root of everything between zero and n is not necessary. Did you mean square? Here’s my solution: def nbDig(n,d): int_list = str([str(x*x) for x in range(0,n+1)]).count(str(d)) return int_list I can test it like so: … Read more
