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**.
Example 1
Input:nums = [2,3,2]
Output:3
Explanation:You cannot rob house 1 (money = 2) and then rob house 3 (money = 2), because they are adjacent.
Example 2
Input:nums = [1,2,3,1]
Output:4
Explanation:Rob house 1 (money = 1) and then rob house 3 (money = 3). Total = 1 + 3 = 4.
