Interview Practice Problems

I thought it might be useful if we create a list of coding puzzles that would be useful for interview practice.

This is a wiki-post that anyone can edit. Feel free to add more problems and/or rearrange these.

These first ones are from the algorithms videos I’m watching. (I’m only on the arrays section so far, but will come back to add more later.)
