Suppose we have a list of items of length \(n\), and we want to consider windows (i.e. contiguous subsequences) of width \(w\) within the list. ⊕ A list of numbers, with contiguous size-3 windows highlighted We can compute the sum of each window by brute force in \(O(nw)\) time, by simply generating the list of all the windows and then summing each. But, of course, we can do better: keep track of the sum of the current window; every time we slide the window one element to the right we can

No, it is not a compiler error. It is never a compiler error. When I used to hang out in the comp.lang.c Usenet group, back when there was a comp.lang.c Usenet group, people would show up fairly often with some program they had written that didn't work, and ask if their compiler had a bug. The compiler did not have a bug. The compiler never had a bug. The bug was always in the programmer's code and usually in their understanding of the language.

Sublinear Time Algorithms Sublinear time is a daunting goal since it allows one to read only a miniscule fraction of the input. There are problems for which deterministic exact sublinear time algorithms are known. However, for most natural problems the algorithm must use randomization and must give an answer which is in some sense approximate. There is a growing body of work aimed at finding sublinear time algorithms for various problems. Recent results have shown that there are classical optim

mdq: jq for Markdown What is mdq? mdq aims to do for Markdown what jq does for JSON: provide an easy way to zero in on specific parts of a document. For example, GitHub PRs are Markdown documents, and some organizations have specific templates with checklists for all reviewers to complete. Enforcing these often requires ugly regexes that are a pain to write and worse to debug.
