I have solved the MinRouterPeripherality task in codility using javascript using Breadth First Search(BFS) approach.
However time complexity is O(N^2). I am really struggling to make performance improvement necessary so I can get the time complexity to possibly O(N) or close to it

To better understand them I tried to write something of a usable list comprehension like those in Haskell and Python. I've asked and had answered a question on SO in the process: Rust macro error:...
Is it possible to automate the array inside the while loop and automatically assign the key name based on the row so I don't have to spell out each one?

I'm expecting this format: yyyy-MM-dd HH:mm:ss.ZZZZZZZ.
Parsing this datetime string using chrono is slow. I've managed to parse it three times faster by naively parsing the string:

if str.len() < 10 {
return None;
}

I have written a python 2 program for a school project to convert from hexadecimal to decimal without using built-in functions and vice versa in python. I would like to know how I can make my code more concise - specifically, the "d_func" function.
