Solve tree and DP problems

This coding round contained two algorithm questions: 1. **Deepest shared ancestor in a binary tree** You are given the root of a binary tree and two distinct nodes `p` and `q` that both exist in the tree. Return the deepest node that is an ancestor of both `p` and `q`. A node may be considered an ancestor of itself. 2. **Maximize money from non-adjacent houses** You are given an integer array `money` where `money[i]` is the amount of money stored in the `i`th house on a street. You may not take money from two adjacent houses on the same night. Return the maximum total amount you can collect.
