CW: Maths, polynomials, random numbers
Challenge: Given a 33 bit shift register based random number generator, shifting 32 times to make a random integer, we observe that a given value will always appear twice in the sequence. Generally unevenly spaced. How to find a value which has the closest repeat?
We could run for 2^33 iterations and keep a record in a many gigabyte array, but I imagine there's a better way.
Boosts OK!
