Here's my attempt at a C++2a Standard Library–friendly "topological sort" algorithm. There are several areas of interest here:
The algorithm is comparison-based and in-place, just like std::sort. This makes it something like $O(n^3)$, which is certainly worse than it ought to be. Can we speed i...
I'm a Javascript learner. I found the below "code1" in freeCodeCamp, I found it complicated and I wrote the "code2". Both are returning the same results. Why is code 1 is this complicated? I did some research and found that "use strict" can't have functions. Could someone help me to understand th...
