31. Write the equation for Geometric Brownian Motion (GBM). 32. Apply Itô's Lemma to find $d(\ln S_t)$ where $S_t$ follows GBM. 33. What is the quadratic variation of Brownian Motion? ($[W, W]_t = t$) 34. Show that $S_t \exp(-W_t + t/2)$ is a martingale. 35. Ornstein-Uhlenbeck Process: Write the SDE for a mean-reverting process. How would you simulate this? Design an algorithm to find the maximum subarray
There are 100 closed lockers in a hallway. A person walks by and opens every locker. A second person closes every second locker. A third person changes the state (opens if closed, closes if open) of every third locker. This continues until 100 people pass. Which lockers remain open at the end?
