Restate the problem precisely. Interviewers reward candidates who pause, define the contract, and name the guarantees before coding.
You are a professional robber planning to rob houses along a street. Each house has a certain amount of money stashed. All houses at this place are arranged in a circle. That means the first house is the neighbor of the last one. Meanwhile, adjacent houses have a security system connected, and it will automatically contact the police if two adjacent houses were broken into on the same night. Given an integer array `nums` representing the amount of money of each house, return the maximum amount of money you can rob tonight without alerting the police.
