Whether we know <math>n</math> or not we can sample <math>k</math> values uniformly by assigning a random value to each element, sorting, and taking the top <math>k</math> values. However, this is not very efficient so instead we can use a <i>priority queue</i> of size <math>k</math> with random priority.
