Introduction
You are on a network of islands which are connected by wooden bridges and you want to see if you can burn every bridge in the island network. However, you can only burn a bridge once you've walked over it.
Once a bridge has been burned, it has gone and you cannot go back over it. N...
I am currently dealing with an analytics problem.
The data consists of historical information of households and products used by them over the period of two decades.
I have outcome variable as product segment which is defined by a a specific segment code.It is denoted by A-Z and 0-9. (Total 35...
In graph theory, an Eulerian trail (or Eulerian path) is a trail in a finite graph which visits every edge exactly once. Similarly, an Eulerian circuit or Eulerian cycle is an Eulerian trail which starts and ends on the same vertex. They were first discussed by Leonhard Euler while solving the famous Seven Bridges of Königsberg problem in 1736. The problem can be stated mathematically like this:
Given the graph in the image, is it possible to construct a path (or a cycle, i.e. a path starting and ending on the same vertex) which visits each edge exactly once?
Euler proved that a necessary condition...
Basically what's documented here:
What formula should be used to determine "hot" questions?
We have a few tweaks:
Succeeding questions from the same site are penalized by increasing amounts. So, the first question from SO in the list gets multiplied by 1.0, the second by 0.98, the third ...

|n,i,j|&n[i..<[_]>::len(n)-j]
Call it as follows:
let a = &[1, 2, 3, 4, 5, 6];
let f = |n,i,j|&n[i..<[_]>::len(n)-j];
f(a, 2, 1)
I had a lot of fun fighting with the borrow checker figuring out what the shortest approach was in order to have it infer the lifetime of a returne...
MacGyver's Toolbox
In this question each answer will get a "toolbox" that can be used to construct a program/function. The toolbox will consist of two things:
a list of programming languages
a list of valid characters
You must write a valid program/function in one of the languages provided ...

This is a simple one: Take a matrix of integers as input, and output the index of the row with the most non-zero elements. You may assume that there will only be one row with the most non-zero elements.
Test cases:
These are 1-indexed, you may choose if you want 0 or 1-indexed.

Well, the traditional generic name for the country club bar is "the nineteenth hole", which suggests The Nineteenth Byte or something like that.
In golf, the nineteenth hole is a slang term for a pub, bar, or restaurant on or near the golf course, very often the clubhouse itself. A standard round of golf has only eighteen holes, so golfers will say they are at the 'nineteenth hole', meaning they are enjoying a drink after the game. The concept is similar to Après-ski in skiing.
The 19th hole on miniature golf courses is often a hole in which if a hole-in-one is scored, one receives a free game.
