What is a queue?
The default program when you create a new project in C++ using either Visual Studio or Eclipse GIVEN that you want a prewritten program (so not if you create an empty project).

return 0;
}
(I will accept any variation of this since it's slightly different depending on which IDE you use.)
Add two unsigned integers using recursion in Python.
What is:
def sum(a, b):
if b == 0:
return a
return 1 + sum(a, b - 1)
(If you have a solution that isn't this but you think that it'll work, I'll pull up an online interpreter and we will check live.)

"What is the shortest way to travel from Rotterdam to Groningen, in general: from given city to given city. [...] One morning I was shopping in Amsterdam with my young fiancée, and tired, we sat down on the café terrace to drink a cup of coffee and I was just thinking about whether I could do this... As I said, it was a twenty-minute invention. In fact, it was published in '59, three years later. The publication is still readable, it is, in fact, quite nice. One of the reasons that it is so nice was that I designed it without pencil and paper. I learned later that one of the advantages of designing without pencil and paper is that you are almost forced to avoid all avoidable complexities."
