Pretty cool! However, some riddles are incorrect, for example this one has two errors:

  def foo( vals ):
    output = vals[0]
    for x in vals[1:]:
      if output < x:
        output = x
    return x

2. The answer should be "The maximum value", not "The minimum value"

Also, it could be nice if after you solve a riddle you would get a new one.

Wouldn’t a better idea be to show a question on Stack Overflow which is somewhat upvoted but still without an accepted answer?

    $ git checkout -b feature

Why would I want to be distracted while doing a task that serves a certain purpose? I must be the only one not just opening new tabs out of boredom :P

The following is incorrect for finding a missing number in a sequence.

  func foo( _ nums: [Int] ) -> Int {
    var sum = 0
    var _ = nums.map {sum += $0}

    return (nums.count * ((nums.count+1) / 2)) - sum
  }

  return ((nums.count+1) * ((nums.count+2) / 2)) - sum

I enjoyed it, but you should allow me to disable random HackerNews links. That's not the purpose of the extension.

Nice! It would be cool if there was some kind of points to denote how many questions we have answered correctly.

Is there a Firefox version?

#include<stdio.h>

int main() { int array[] = { 1, 2, 3, 4, 5}; int *ptr; ptr = a; ptr++;

    return 0; 

This won't compile, but the answer says it should be 2
