I am deeply impressed by your use of pen and paper, even the clever little slider. Pen and paper is what helps me the most with thinking about programming.

Thanks for noticing the little details! Agreed pen/paper is a super underrated tool. The effect at 1:16 was cool to figure out. I tried the blur the lines between physical and digital.

The question said "you may assume each input has exactly one solution"
Hence the solution either has no number repeated in the array, or the solution is a repeated number in 2 indices.

[@GordonZhu]

Those are *not* the only cases with repeated numbers. You could also have a case like [2, 2, 2, 2, 7, 3] where the target is 10.
