Here is some list functions based on Martin v. Löwis’s representation: where w = sys.stdout.write Although doubly linked lists are famously used in Raymond Hettinger’s ordered set recipe, singly linked lists have no practical value in Python. I’ve never used a singly linked list in Python for any problem except educational. Thomas Watnedal suggested a … Read more
Well, the $key => $value in the foreach loop refers to the key-value pairs in associative arrays, where the key serves as the index to determine the value instead of a number like 0,1,2,… In PHP, associative arrays look like this: In the PHP code: $featured is the associative array being looped through, and as … Read more
The current answers are good, but do not talk about how they are just syntactic sugar to some pattern that we are so used to. Let’s start with an example, say we have 10 numbers, and we want a subset of those that are greater than, say, 5. For the above task, the below approaches … Read more
I just installed Node.js and npm (for additional modules). How can I update Node.js and the modules which I’m using to the latest versions? Can npm do it, or do I have to remove and reinstall Node.js and npm to get the next versions? I followed this steps in the npm section.
What is the difference between splice and slice?
It documents your intent – you will be storing small numbers, rather than a character. Also it looks nicer if you’re using other typedefs such as uint16_t or int32_t.
Two things I see. First, you’re mixing chars with ints in the matrix array. Second, you’re printing the elements of matrix out to a file using the “%s” format. “%s” expects a null-terminated string where as you are passing chars and ints. This will cause the printf to try and access memory that is out-of-bounds, … Read more
item is most likely a string in your code; the string indices are the ones in the square brackets, e.g., gravatar_id. So I’d first check your data variable to see what you received there; I guess that data is a list of strings (or at least a list containing at least one string) while it … Read more
Use git rebase -i <after-this-commit> and replace “pick” on the second and subsequent commits with “squash” or “fixup”, as described in the manual. In this example, <after-this-commit> is either the SHA1 hash or the relative location from the HEAD of the current branch from which commits are analyzed for the rebase command. For example, if … Read more
How about: This is extended slice syntax. It works by doing [begin:end:step] – by leaving begin and end off and specifying a step of -1, it reverses a string.
